Triisopropanolamine (TIPA) is a tertiary amine with three isopropanol groups, widely used as a corrosion inhibitor, pH adjuster, and emulsifier in industrial cleaning agents, metalworking fluids, and personal care products. It also serves as a cross-linking agent in rubber and coatings, and as a neutralizer and stabilizer in pesticide formulations. It is also employed in gas treating to remove acidic gases like CO₂ and H₂S. This chemical has a CAS number of 122-20-3, a molecular formula of N(CH₂CH(CH₃)OH)₃, and a molecular weight of 191.28 g/mol. It is stored at ambient conditions and carries a signal word of "Warning" under GHS classification. Molekula supplies Triisopropanolamine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
