4,4'-Methylenedianiline

4,4-Diaminodiphenylmethane, sodium chloride (3:1)

C13H14N2 (198.1157)


4,4’-Methylenedianiline (MDA) is an industrial chemical that is produced and used industrially as a precursor to polyamides, epoxy resins, and polyurethane foams (PMID: 20621954). It is a primary aromatic amine, belonging to the family of compounds known as Diphenylmethanes. Diphenylmethanes are compounds consisting of methane with two of the hydrogen atoms replaced by phenyl groups. MDA is used mainly as a precursor to 4,4 ́-methylene diphenyl diisocyanate (MDI), which is a precursor to many polyurethane foams. To generate MDI, which is a highly reactive isocyanate, MDA is treated with phosgene. Workers exposed to MDI may develop sensitization, leading to occupational asthma. MDI is metabolized in the body and secreted in the urine as MDA, Therefore MDA is a urinary biomarker of MDI exposure. On its own, MDA is a known animal carcinogen, and human hepatotoxin. MDA produces genotoxic effects by forming DNA adducts in the liver and inducing DNA damage to hepatocytes (PMID: 32038824). The Occupational Safety and Health Administration has set a permissible exposure limit at 0.01 ppm over an eight-hour time-weighted average, and a short-term exposure limit at 0.10 ppm.
