Product Name:2,4,6-Trimethyl-3,5-diaminobenzenesulfonic acid
English Name:2,4,6-Trimethyl-3,5-diaminobenzenesulfonic acid
CAS No.:32432-55-6
Aliases:3,5-Diamino-2,4,6-trimethylbenzenesulfonic acid, 2,4,6-Trimethyl-3,5-diaminobenzene-1-sulfonic acid
Molecular Formula:C9H14N2O3S
Physical Properties:Molecular weight: 230.29. White to light yellow crystalline powder, odorless or with a slight odor. Readily soluble in water and alcohols; slightly soluble in ether, acetone and other organic solvents; insoluble in benzene and petroleum ether. Melting point above 300 °C (decomposition). It possesses reducing properties typical of aromatic amines and may gradually oxidize and discolor upon prolonged exposure to air. Its aqueous solution is acidic and forms salts with bases.
Uses:Mainly used as a dye intermediate for the synthesis of azo dyes, reactive dyes and acid dyes. It is also used in the preparation of optical brighteners, pharmaceutical and pesticide intermediates. The sulfonic acid group imparts good water solubility to dyes, while the amino groups can undergo diazotization and coupling reactions to produce various fine chemicals.
Technical Specifications:
Assay (on dry basis): ≥98.0%
Melting point: >300 °C (decomposition)
Loss on drying: ≤0.5%
Water-insoluble matter: ≤0.1%
Appearance: white to light yellow crystalline powder
