Description
M-Toluidine (CAS 108-44-1) is an aromatic amine also known as 3-toluidine, m-Tolylamine, and m-Toluamine. It carries EC number 203-583-1 and molecular formula C7H9N. No E-code applies to this substance.
In textile and leather processing, m-Toluidine functions as a dye intermediate, where its primary amine group reacts with diazonium salts to form stable azo colorants. In polymer and rubber applications, it acts as a cross-linking agent, forming covalent bonds between polymer chains to improve structural integrity. Personal care formulators use it as a hair dye precursor in oxidative coloring systems.
M-Toluidine is supplied as a liquid grade and falls under REACH regulation, requiring an up-to-date Safety Data Sheet for EU trade. Procurement teams should confirm supplier registration status and substance authorization requirements before ordering. Standard packaging formats include drums and IBC containers for bulk industrial supply.
