APPLICATIONS
N,N′-Dimethyl urea is used for synthesis of caffeine, theophylline, pharmachemicals, textile aids, herbicides and others.
In the textile processing industry N,N′-Dimethyl urea is used as intermediate for the production of formaldehyde-free easy-care finishing agents for textiles.
The estimated world production of N,N′-Dimethyl urea is estimated to be less than 25,000 tons.
Mainly N,N′-Dimethyl urea is used for fiber treatment agent and a crosslinking agent, which does not have formalin; cellulose nitrate used colloidal agent; the goods and the resulting mixture was used as a preservative formalin, deodorant; can be used to having ethylene propylene copolymer acrylic resin; used as pharmaceutical raw materials, preparation of caffeine, N, N`- acetyl dimethyl urea and sodium cyanide, 6-AMINO-1,3-DIMETHYL-5-NITROSOURACIL and the like; the product added to the saccharine can be improved the sweetness.
N,N′-Dimethylurea can be used As a starting material to synthesize N,N′-dimethyl-6-amino uracil.
In combination with β-cyclodextrin derivatives, N,N′-Dimethylurea can be used to form low melting mixtures (LMMs), which can be used as solvents for hydroformylation and Tsuji-Trost reactions.
N,N′-Dimethylurea can be used To synthesize N,N′-disubstituted-4-aryl-3,4-dihydropyrimidinones via Biginelli condensation under solvent-free conditions.
N,N′-Dimethylurea can be used as an intermediate in the synthesis of theophylline and caffeine, and also used in the production of fiber treatment agents
DESCRIPTION
N,N′-Dimethyl urea (DMU) (IUPAC systematic name: 1,3-Dimethylurea ) is a urea derivative and used as an intermediate in organic synthesis.
N,N′-Dimethyl urea is a colorless crystalline powder with little toxicity.
N,N'-dimethyl urea is a member of the class of ureas that is urea substituted by methyl groups at positions 1 and 3.
Appearence of N,n'-dimethyl urea is as colorless crystals.
N,N′-Dimethyl urea belongs to the class of organic compounds known as ureas.
Ureas are compounds containing two amine groups joined by a carbonyl (C=O) functional group.
N,N′-Dimethyl urea is a primary metabolite.
Primary metabolites are metabolically or physiologically essential metabolites.
They are directly involved in an organism’s growth, development or reproduction.
N,N′-Dimethyl urea is a urea derivative and used as an intermediate in organic synthesis.
N,N′-Dimethyl urea is a colorless crystalline powder with little toxicity.
Also, N,N′-Dimethyl urea is used for synthesis of caffeine, pharmachemicals, textile aids, herbicides and other.
In the textile processing industry N,N′-Dimethyl urea is used as intermediate for the production of formaldehyde-free easy-care finishing agents for textiles.
In the Swiss Product Register there are 38 products containing N,N′-Dimethyl urea, among them 17 products intended for consumer use.
Product types are e.g. paints and cleaning agents.
The content of N,N′-Dimethyl urea in consumer products is up to 10 %.
Use of N,N′-Dimethyl urea in cosmetics has been proposed, but there is no information available as to its actual use in such applications.
N,N′-Dimethyl urea is a gray-white flake crystal.
The melting point of N,N′-Dimethyl urea is 101-104 °c.
Boiling point of N,N′-Dimethyl urea is 268~270 deg C.
The relative density of N,N′-Dimethyl urea is 1. 142.
N,N′-Dimethyl urea is Soluble in water, ethanol, acetone, benzene and ethyl acetate, does not dissolve in ether and gasoline.
Nitrogen can be generated by reaction with sodium hypochlorite in the presence of a base.
N,N′-Dimethyl urea can also react with chlorine, aldehyde, ketone, inorganic acid, nitrous acid and the like.
N,N′-Dimethyl urea, also known as 1,3-dimethylcarbamide, presents as a white to almost white crystalline powder.
Store N,N′-Dimethyl urea in a cool and dark place at ambient temperatures.
N,N′-Dimethyl urea is known to be incompatible with oxidizing agents and should not be stored or handled in their vicinity.
N,N′-Dimethyl urea may cause damage to organs, such as the kidneys, through prolonged or repeated exposure.
FIRST AID
EYES:
First check the victim for contact lenses and remove if present.
Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center.
Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician.
IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
SKIN:
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing.
Gently wash all affected skin areas thoroughly with soap and water.
If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
INHALATION:
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air.
If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital.
Provide proper respiratory protection to rescuers entering an unknown atmosphere.
Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.
INGESTION:
DO NOT INDUCE VOMITING.
If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center.
Be prepared to transport the victim to a hospital if advised by a physician.
If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body.
DO NOT INDUCE VOMITING.
IMMEDIATELY transport the victim to a hospital.
