Usage

General Description

4,6-diaminotoluene-3-sulphonic acid is a chemical compound that consists of a benzene ring with an amino group and a sulfonic acid group attached at different positions. It is commonly used in the production of dyes, particularly azo dyes, as a diazo component. It is also used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. The chemical is a white to off-white solid at room temperature and has a strong acidic character due to the presence of the sulfonic acid group. It is considered to be potentially hazardous to human health and the environment, as it can cause irritation to the skin, eyes, and respiratory system, and can be harmful if ingested or inhaled.
