Octamethylene diamine（Cat No.:R071306）, also known as 1,8-diaminooctane, is a colorless to pale yellow liquid or solid with a strong amine odor. This aliphatic diamine is primarily used as a monomer in the synthesis of polyamides, such as nylon-8,8, and in epoxy curing agents, surfactants, and specialty polymers. Its linear structure offers flexibility and chemical reactivity, making it valuable in coatings, adhesives, and textile treatments. Octamethylene diamine is corrosive and can cause severe skin and eye irritation, so strict safety protocols and personal protective equipment are essential when handling this industrial chemical.
