Chemical Properties

White Redish Powder

Uses

2,5-Diaminotoluene sulfate is a primary intermediate in various permanent hair dyes.

Definition

ChEBI: 2,5-diaminotoluene sulfate is an organic sulfate salt obtained by combining 2,5-diaminotoluene with one molar equivalent of sulfuric acid; occurs as an intermediate during hair dye formulation. It has a role as an allergen. It is an organic sulfate salt and a diamine. It is functionally related to a 2-methyl-1,4-phenylenediamine.

General Description

2,5-Diaminotoluene sulfate occurs as an intermediate during hair dye formulation.

Flammability and Explosibility

Non flammable

Safety Profile

Poison by ingestion and intraperitoneal routes. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx and SOx. See also SULFATES.
