p-Toluidine is an aromatic amine used primarily in the synthesis of dyes, pharmaceuticals, and agrochemicals, as well as in rubber and polymer production. It serves as a key intermediate in manufacturing products like azo dyes, pigments, and certain pesticides. This colourless to white crystalline solid (melting point about 43–45 °C) has a CAS number of 106-49-0, with the molecular formula C7H9N (written in condensed form as C6H4CH3NH2) and a molecular weight of 107.1531 g/mol. It should be stored at ambient conditions under proper ventilation, as it carries a Danger signal word due to its toxic and hazardous properties. Molekula supplies p-Toluidine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
