1,8-Naphthalenediamine is an aromatic diamine compound widely used in the synthesis of dyes, pigments, and pharmaceutical intermediates, particularly in the production of azo dyes and organic light-emitting diodes (OLEDs). It is also employed as an antioxidant additive for lubricating oils and as an analytical reagent for detecting selenium and nitrites. It serves as a key building block in chemical manufacturing due to its reactive amine groups. This product has a CAS number of 479-27-6, with a molecular formula of C10H10N2 and a molecular weight of 158.20 g/mol. It is stored at ambient conditions but requires careful handling due to its hazardous nature, as indicated by its "Danger" signal word. Molekula supplies 1,8-Naphthalenediamine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
