Product Name:Naphthol AS-KG
English Name:Naphthol AS-KG
CAS No.:12221-03-3
Aliases:C.I. Azoic Coupling Component 107, 3-Hydroxy-N-(4-chloro-2,5-dimethoxyphenyl)-2-naphthamide
Molecular Formula:C19H16ClNO4
Physical Properties:Light brown to beige powder; molecular weight approximately 357.79. Insoluble in water, slightly soluble in ethanol, soluble in acetone and benzene; dissolved in concentrated sulfuric acid to give a yellow solution. Melting point about 246°C with decomposition. Air-stable; keep sealed and protected from light.
Uses:Mainly used as a coupling component in ice dyes (insoluble azo dyes) for dyeing and printing of cellulosic fibers such as cotton, hemp and viscose. It couples with diazotized color bases to produce deep, fast dyes, and is also used in the synthesis of organic pigments and dye intermediates.
Technical Specifications:
Appearance: light brown to beige powder.
Assay (HPLC) ≥98%.
Melting point: about 246°C (decomposition).
Moisture ≤0.5%.
Ash ≤0.5%.
