Product Description

Light Stable Crystalline 2-Naphthol CAS 135-19-3 for Dye Intermediate Production

Product Overview

2-Naphthol, also named β-Naphthol with CAS registry number 135-19-3, is an aromatic phenolic compound. It appears as white glossy crystalline flakes or powder under normal temperature, carrying mild phenolic scent. This material features stable crystal form, moderate chemical activity and controllable coupling reaction performance. It serves as a core synthetic raw material in colorant manufacturing and rubber auxiliary industries with consistent processing performance.

Physical & Chemical Properties

This aromatic solid dissolves well in alcohol solvents and alkaline aqueous solution, with limited solubility in cold water. It shows stable thermal performance within common processing temperature ranges, yet turns darker under long-term light exposure. Its phenolic structure supports substitution and coupling reactions required for pigment synthesis. Sealed dark storage effectively slows discoloration and maintains original crystalline texture for long-term industrial use.
