3-(METHYLTHIO)ANILINE Usage And Synthesis
Chemical Properties clear dark brown liquid
Uses Pharmaceutical intermediate.
Hazard See aniline.
Safety Profile Moderately toxic by ingestion.When heated to decomposition it emits toxic vapors ofNOx and SOx.
Purification Methods Purify the aniline by fractional distillation in an inert atmostphere. It has UV max at 226 and 300nm. [Bordwell & Cooper J Am Chem Soc 74 10581952.] The N-acetyl derivative has m 78-78.5o (from aqueous EtOH). The hydrochloride has m 260-261o (aqueous EtOH/HCl) or m 225-227o (EtOH/Et2O).
