Structure of 2,4-Diaminophenol (CAS NO.95-86-3):

IUPAC Name: 2,4-Diaminophenol

2,4-Diaminophenol Uses

Its dihydrogen chloride salt is used as a photographic developer. As amidol ages 2,4-Diaminophenol (CAS NO.95-86-3) changes color to a dark red-brown. Developing dishes and equipment used to prepare amidol solutions are also frequently stained brown, a stain that is very persistent.

2,4-Diaminophenol Safety Profile

Poison by intraperitoneal route. Mutation data reported. When heated to decomposition it emits toxic fumes of NO_x. See also AMINES and PHENOL.

2,4-Diaminophenol Specification

2,4-Diaminophenol ,its cas register number is 95-86-3. It also can be called Amidol ; and Phenol, 2,4-diamino- . 2,4-Diaminophenol (CAS NO.95-86-3) was introduced as a developing agent for photographic papers in 1892, and is unusual amongst developers as it works most effectively in slightly acid conditions rather than the strongly alkaline conditions required for most other developers.
