N-Methyldiphenylamine Usage And Synthesis

Chemical Properties

CLEAR YELLOW LIQUID

Uses

N-Methyldiphenylamine may be used for the synthesis of phosphonium ion salts. It may also be used as a starting reagent for the preparation of bis(4-carboxyphenyl)-N-methylamine (H₂CPMA).

Uses

manufacture of dyes; as reagent similar to diphenylamine.

Synthesis Reference(s)

Journal of Medicinal Chemistry, 23, p. 184, 1980 DOI: 10.1021/jm00176a015

General Description

N-Methyldiphenylamine is an aromatic tertiary amine. It undergoes transformation to N-methylcarbazole (C) via a photochemical reaction.

Hazard

Toxic by ingestion.
