Description

m-Toluidine (CAS 108-44-1 ), also known as m-aminotoluene, is an aromatic amine used as a chemical intermediate in the synthesis of dyes, pigments, and specialty organic compounds. It serves as a building block for azo colorants and downstream chemical manufacturing across multiple industrial sectors. In textile and leather processing, it is used to produce azo dyes that deliver consistent color performance. Pigment manufacturers rely on it as a coupling or diazotization component in the production of organic colorants for inks and printing formulations. This ensures high-quality results in various industrial printing applications. In plastics and polymer systems, it functions as a curing agent or cross-linker in epoxy and resin formulations where controlled reactivity is required. This makes it essential for specialized material engineering. Cosmetic and personal care manufacturers source it as a precursor in the synthesis of approved colorant intermediates used in hair dye formulations. Its chemical properties allow for precise color development. m-Toluidine is supplied as a liquid at ambient conditions, typically available in technical grade for industrial synthesis applications. Standard packaging includes drums and intermediate bulk containers (IBCs). These packaging options are suited for bulk procurement and large-scale manufacturing needs. Purity specifications generally range from 98% to 99%+, ensuring high performance in sensitive chemical reactions. Documentation is available to support quality assurance and regulatory compliance requirements. This ensures that all industrial standards are met for safety and efficacy in global supply chains.
