4-(Methylmercapto)aniline Chemical Properties,Uses,Production

Chemical Properties

clear orange to brown-red liquid

Definition

ChEBI: 4-(methylthio) aniline is an aryl sulfide.

Synthesis Reference(s)

Tetrahedron Letters, 35, p. 7867, 1994 DOI: 10.1016/0040-4039(94)80139-8

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 atmosphere. The hydrochloride has m 242-246o (from aqueous EtOH/HCl). The sulfone has m 137o (from H2O), pK2 5 1.48, and the sulfone hydrochloride has m 260-261o (from aqueous EtOH/HCl).
