2-Bromopropane has proved to be a useful reagent for amino acids dissolved in dimethylsulfoxide/sodium hydride, except for the determination of arginine.
Methylation of acids with diazomethane has also been used for metabolic profiling despite the formation of artefacts.

Resin-mediated methylation of polyfunctional acids found in fruit juices has also proved successful.
Fumaric, succinic, malic, tartaric, isocitric and citric acids, isolated from fruit juices by trapping onto anionic ion exchange resins, can be efficiently converted to methyl esters by reaction with methyl iodide in both supercritical carbon dioxide and acetonitrile.

To provide for the analysis of even short chain fatty acids in serum, a procedure has been developed with benzyl bromide.
This has been successfully employed for serum and urine organic acid profiling.
The method cannot be used for citric acid or sugar-related acids.

Exposure to 2-Bromopropane has been associated with adverse reproductive effects in men and women.
There are also some reports suggesting that maternal formaldehyde exposure is related to delayed conception and miscarriage, and exposure to trinitrotoluene or trichloroethylene may be harmful for the reproductive health of men.
Formamide, dimethylformamide and n-methyl-2-pyrrolidone have also been shown to cause fetotoxic and teratogenic effects in laboratory animals, but there are no data on their effects in humans.

In summary, the epidemiologic evidence suggests that high maternal exposure to solvents may represent a hazard for the developing fetus and may impair female fertility.
The results for male fertility are less conclusive.

The findings on individual solvents must also be interpreted with caution, because coincident exposure to several agents makes 2-Bromopropane difficult to ascribe adverse effects to a specific compound.
Nevertheless, the study results are supportive of adverse effects of some glycol ethers, tetrachloroethylene, toluene, benzene and carbon disulfide on reproduction.
2-Bromopropane would be prudent to minimize exposure to organic solvents.
