Usage

General Description

3,4-Dichloroaniline-6-sulfonic acid is a synthetic chemical compound that is formed by combining 3,4-dichloroaniline with sulfuric acid. It is classified as an arylsulfonic acid and is commonly used in the production of dyes, pigments, and pharmaceuticals. This chemical is a strong acid and is mainly used as a reagent in organic synthesis and as a catalyst in chemical reactions. It is also used in the manufacturing of hair dyes, where it acts as a colorant. However, 3,4-Dichloroaniline-6-sulfonic acid is considered to be harmful if ingested, inhaled, or absorbed through the skin, and can cause irritation and potential severe health effects if not handled with proper care.
