Trimethylhexamethylenediamine (TMHMD) is a branched aliphatic diamine used primarily in the synthesis of polyamides, polyurethane elastomers, and epoxy curing agents, offering improved flexibility and thermal stability. This chemical is a clear, colorless liquid with a strong amine odor, essential for industrial polymer formulations. Trimethylhexamethylenediamine (CAS 25513-64-8) has the molecular formula C9H22N2 and a molecular weight of 158.28. It is stored at ambient conditions but requires careful handling due to its hazardous nature, marked by a "Danger" signal word. Molekula supplies Trimethylhexamethylenediamine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
