Description and Uses
N-Methylaniline is a yellow to light brown oily liquid with a weak, ammonia-like odor. Turns reddishbrown if left standing. The odor threshold is 1.7 ppm. Molecular weight= 107.17; Specific gravity (H2O:1)= 0.99;Boiling point=195.6℃; Freezing/Melting point=57.2℃; Vapor pressure= 0.3 mmHg at 20℃; Flash point=79.4℃. Hazard Identification (based on NFPA-704 M Rating System): Health 2, Flammability 2, Reactivity 0. Practically insoluble in water.
N-Methylaniline is used as a solvent and in organic synthesis. It is used in the production of cationic brilliant red FG, cationic pink B, reactive yellow brown KGR, etc. in the dye industry. N-methylaniline is an intermediate in the synthesis of the insecticide buprofezin and the herbicide mefenacet.
