1,5-Diaminopentane (CAS 462-94-2) is a colorless, hygroscopic diamine used primarily in polymer synthesis, pharmaceutical intermediates, and the production of chelating agents. It serves as a key building block in nylon-5,5 and other specialty polymers, as well as in the manufacture of agrochemicals and corrosion inhibitors. This chemical has the molecular formula C5H14N2 with a molecular weight of 102.18 g/mol. It should be stored at ambient conditions, though it is highly reactive with moisture and carbon dioxide. The product carries a Danger signal word due to its severe skin and eye irritation, as well as its corrosive and flammable properties. Handling requires appropriate PPE and ventilation. Molekula supplies 1,5-Diaminopentane from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
