Spin trapping of nitric oxide radicals
By the technique of spin trapping, complexes of dithiocarbamates with iron provide one of the very few methods to study the formation of nitric oxide (NO) radicals in biological materials. Although the lifetime of NO in tissues is too short to allow detection of this radical itself, NO readily binds to iron-dithiocarbamate complexes. The resulting mono-nitrosyl-iron complex (MNIC) is stable, and may be detected with Electron Paramagnetic Resonance (EPR) spectroscopy.

Sodium dimethylthithiocarbamate's production and use as a disinfectant, corrosion inhibitor, coagulant, vulcanizing agent, chelating agent, and fungicide may result in its release to the environment through various waste streams. Sodium dimethylthithiocarbamate is used in water treatment, the rubber industry and is a registered biocide for cutting oils and aqueous systems in industries such as leather tanning and paper manufacturing. It is also used as an antimicrobial agent in paints. If released to air, sodium dimethylthithiocarbamate will exist solely in the particulate phase in the ambient atmosphere, since it is a salt and will be nonvolatile. Particulate-phase sodium dimethylthithiocarbamate will be removed from the atmosphere by wet and dry deposition. If released to soil, sodium
dimethylthithiocarbamate is expected to have very high mobility based upon an estimated Koc of 2.2. The estimated pKa of sodium
dimethydithiocarbamate is 5.4, indicating that this compound will primarily exist in the dissociated form at environmentally relevant pHs; therefore, volatilization from moist soil surfaces is not expected to be an important fate process. Sodium dimethylthithiocarbamate not expected to volatilize from dry soil surfaces since it is a salt and will be nonvolatile. If released into water, sodium dimethylthithiocarbamate is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Sodium dimethylthithiocarbamate, present at 100 mg/L, reached 2% of its theoretical BOD in 28 days at 25 °C using an activated sludge inoculum at 30 mg/L and the Japanese MITI test; however, this result may be due to the biocidal properties of sodium dimethylthithiocarbamate. In an anaerobic degradation test with sodium dimethylthithiocarbamate, tetramethyl thiuram disulfide and tetramethyl thiuram monosulfide were the major decomposition products. The estimated pKa of the organic portion of sodium dimethydithiocarbamate indicates that this compound will primarily exist in the dissociated form at environmentally relevant pHs; therefore, volatilization from water surfaces is not expected to be an important fate process. Bioconcentration is not expected to be a significant fate for sodium dimethylthithiocarbamate, due to its rapid hydrolysis at neutral and acidic pH and its ionic character. Hydrolysis half-life of 18 minutes, 25.9, and 433.3 hours were reported for sodium dimethylthithiocarbamate at pH 5, 7, and 9, respectively. Photolysis in aqueous solution and on soil was found to be an important degradation process for a related compound, ziram, and may also be important for sodium dimethylthithiocarbamate. Occupational exposure to sodium dimethylthithiocarbamate may occur through inhalation and dermal contact with this compound at workplaces where sodium dimethylthithiocarbamate is produced or used. Most large industrial users of sodium dimethylthithiocarbamate for water treatment use mechanized material handling systems, and exposure to workers would be expected to be minimal. The greatest potential for dermal and inhalation exposure to sodium dimethylthithiocarbamate is expected at the packing station at the manufacturing site and to a lesser extent during activities at the consumer site.

Chemical Properties
White Solid
Uses:An inhibitor of superoxide dismutase, having both antioxidant and oxidant effects.
Uses:The -log KH of the acid is 3.4 in aqueous medium. From this fact and the distribution ratio it follows that the reagent can be extracted quantitatively from acidic media (pH < 4) with organic solvents, while at pH > 8 it remains quantitatively in the aqueous phase.
Sodium dimethyldithiocarbamate reacts with even more metal ions than does dithizone. However, its analytical application is seriously limited by its considerably lower stability in acidic aqueous media. According to the examinations of Bode,the reagent undergoes considerable decomposition within 5 minutes at pH 5. The analytical application of the reagent is therefore restricted to a very narrow pH range. There is no chance with this reagent to enhance the analytical selectivity of extractions by making use of the difference between the stabilities of its complexes with various metal ions and to choose the pH of the reaction mixture accordingly. Notwithstanding, some authors suggest extraction procedures from acidic media, for instance in the cases of such stable complexes as those of copper( II), nickel(II) and bismuth(III). However, in these procedures extraction must be done immediately after acidification of the solution, and even then the error caused by decomposition of the reagent must be taken into account. The analytical selectivity of the complexation reactions of dimethyldithiocarbamate can be enhanced by using various auxiliary complexing and masking agents. EDTA is particularly useful for this purpose, but there are also other complexing agents, such as cyanide or citrate.
The reagent does not absorb in the visible region (>400 nm). On the other hand, its metal complexes are generally coloured, which makes possible the application of the reagent for spectrophotometric measurements. For instance, its cobalt complex is green (absorption maximum at 650 nm), the copper complex brown (absorption maximum at 440 nm), the iron(III) complex red (515 nm), etc. It can be seen that dimethyldithiocarbamate compares favourably with dithizone and oxine, as one of the most useful extracting and spectrophotometric agents in analytical chemistry. In the following some analytical procedures using dimethyldithiocarbamate are described.Besides being well proved in practice, the procedures presented may also serve as illustrations of how to develop other solvent extraction analytical procedures.
Dimethyldithiocarbamate has also proved suitable for the enrichment and isolation of traces of metals. For instance, the metal content of brine or the washings obtained in the purification of contaminated air can be extracted with a solution of dimethyldithiocarbamate in ethyl propionate. The ethyl propionate solution can be used directly for atomic absorption spectroscopic measurement. The sensitivity of the measurement is much higher in this medium than in water.
General Description:Odorless white or slightly brown or slightly pink crystals.
Air & Water Reactions Water soluble. Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids.
Reactivity Profile:Sodium dimethyldithiocarbamate is not compatible with strong oxidizing agents. Aqueous solutions slowly decompose to form carbon disulfide and an amine. Such decompositions are accelerated by acids. Addition of acid to the aqueous solution produces a white turbidity .
Fire Hazard:Flash point data for Sodium dimethyldithiocarbamate are not available; however, Sodium dimethyldithiocarbamate is probably combustible.

Sodium dimethyldithiocarbamate uses and applications include: Intermediate; pesticide; fungicide; corrosion inhibitor; rubber accelerator; biocide, fungicide, and algicide in water treatment; heavy metal precipitant to remove metals from wastewater streams; biocide in paper sizing, adhesives, cutting fluids; polymerization shortstop; termination agent for SB rubber production; antimicrobial in cane-sugar and beet-sugar mills; in food packaging adhesives; slimicide in food-contact paperpaperboard; accelerator for food-contact rubber articles for repeated use.

Sodium dimethyldithiocarbamate (SDMC) has been used in a variety of pesticidal applications as insecticide, fungicide, miticide, and microbicide. The dithiocarbamates (DCs) are basically cytotoxic and regarded as broad-spectrum biocides. The DCs are the half amides of dithiocarbamic acid. They have strong metal-binding characteristics and interact with sulfhydryl-containing compounds. They have been used on a large scale in agriculture as pesticide and fungicide, in the rubber industry as vulcanization accelerators, and in research as enzyme inhibitors. Sodium dimethyldithiocarbamate has been extensively used as an analytical reagent for copper and nickel. Studies do not provide evidence that Sodium dimethyldithiocarbamate is a selective or specific reproductive or developmental toxin but it is considered an immunosuppressant in chronic exposure.

Description
