Aniline
CAS Number: 62-53-3
Aniline is the fundamental aromatic amine intermediate used in the synthesis of azo dyes, reactive dyes, and a wide range of organic pigments. As a primary building block for the dye and pigment industry, it undergoes diazotization reactions to form diazonium salts that couple with various coupling components. Chemzip supplies industrial-grade aniline meeting strict purity specifications for dyestuff manufacturers worldwide.
