About C8H11N (Dimethylaniline, DMA)

N,N-Dimethylaniline (C₈H₁₁N, DMA) is an aromatic amine consisting of a benzene ring substituted with a dimethylamino group. It is a colorless to pale yellow oily liquid with a characteristic amine-like odor, which darkens upon exposure to air and light. Dimethylaniline is widely used as an intermediate in the production of dyes, antioxidants, and photographic chemicals. It also serves as a solvent and a reagent in organic synthesis. Due to its toxic and potentially carcinogenic properties, it should be handled with care in well-ventilated environments. Chemical formula: C₆H₅N(CH₃)₂

Other names: C8H11N, Dimethylaniline, DMA, N,N-Dimethylaniline, C₈H₁₁N, DMA, N-Methylaniline, N-methyl-, N,N-Dimethylbenzenamine, Benzenamine, N,N-dimethyl-, Aniline, dimethyl-, Dimethylphenylamine
