Description

5-Chloro-2-methylaniline (CAS 95-79-4 ), also known as 5-chloro-o-toluidine and 2-amino-4-chlorotoluene, is an aromatic amine intermediate used in the synthesis of azo dyes, pigments, and specialty chemicals. Its reactive amine group makes it a building block for colorant and polymer systems across multiple manufacturing sectors. In textile and leather dyeing, it functions as a diazonium coupling precursor for azo dye production. This enables the manufacture of fast, vibrant colorants applied directly to fiber substrates. Pigment manufacturers use it to produce organic pigments incorporated into printing inks and packaging coatings. Color strength and substrate adhesion are critical performance criteria in these applications. In polymer and plastics processing, it contributes to cross-linking and curing systems, improving structural integrity. Personal care formulators sourcing approved colorant intermediates may evaluate it for cosmetic dye synthesis, subject to regional regulatory compliance. The material is supplied as a liquid or low-melting solid. Physical state depends on purity and temperature conditions during handling. Technical grade is the standard commercial offering, with high-purity grades available for sensitive synthesis applications. These high-purity options are ideal for processes requiring tighter specification control. Bulk and drum quantities are typical for industrial procurement, with smaller packaging available for laboratory use. Contact us for supply of 5-chloro-2-methylaniline Request Quote
