Description
2-Naphthylamine, also known as BNA or beta-Naphthylamine, is an aromatic amine with CAS number 91-59-8 and EC number 202-080-4. It carries the molecular formula C10H9N and is also referenced under trade identifiers including C.I. 37270 and AKOS AUF0416. No E-code designation applies to this substance.
In industrial contexts, 2-Naphthylamine functions primarily as a polymerization initiator, where it acts as a chain-transfer agent or stabilizer in controlled polymer synthesis processes. It has historically served as an intermediate in dye manufacturing within the textile and leather sectors, and finds limited application in pharmaceutical and agrochemical research as a chemical building block.
2-Naphthylamine is supplied in powder form and classified under HS code 29214500. Due to its classification as a Category 1A carcinogen under REACH Annex XVII, procurement requires strict regulatory compliance, and supply is restricted to authorized professional and research applications within the European Union.
