Description

2-Naphthylamine (CAS 91-59-8 ), also known as beta-naphthylamine, is an aromatic amine historically used as a chemical intermediate in the synthesis of dyes, rubber antioxidants, and pharmaceutical compounds. Its primary commercial role is as a building block in organic synthesis, where it contributes to the construction of complex nitrogen-containing ring systems for various industrial applications. In dye manufacturing, it serves as a precursor to azo dyes used in textile and leather coloring processes. Agrochemical producers have utilized it in the synthesis of certain pesticide intermediates. The naphthalene-amine structure provides a reactive site for further functionalization. Pharmaceutical intermediate synthesis draws on its reactivity to build naphthalene-based active compound scaffolds. It has also appeared in rubber processing chemistry as a starting material for antioxidant production. This versatility makes it a valuable, though highly regulated, component in specialized chemical manufacturing. 2-Naphthylamine is supplied as a solid crystalline material. Technical-grade material is the standard commercial form available to industrial buyers seeking high-purity precursors for synthesis. Due to significant regulatory restrictions in many jurisdictions, including classification as a confirmed human carcinogen, procurement requires careful verification of local compliance requirements before sourcing.
