N-Methylaniline (NMA) is an aniline derivative. It is an organic compound with the chemical formula C₆H₅NH(CH₃). The substance is a colorless viscous liquid, Samples turn brown when exposed to air. The chemical is insoluble in water. It is used as a latent and coupling solvent and is also used as an intermediate for dyes, agrochemicals and other organic products manufacturing. NMA is toxic and exposure can cause damage to the central nervous system and can also cause liver and kidney failure. The comprehensive evaluation of N-methylaniline by the Bureau for Chemical Substances in Poland, completed in 2024 as a part of the European Union's REACH regulation, has confirmed significant concerns regarding the carcinogenicity and mutagenicity of N-methylaniline.
