3-Hydroxy-2-naphthoic acid CAS 92-70-6

What is 3-Hydroxy-2-naphthoic acid CAS 92-70-6?

3-Hydroxy-2-naphthoic acid CAS 92-70-6, sometimes referred to as BON acid, is an important aromatic carboxylic acid belonging to the naphthoic acid family. It is primarily produced through the Kolbe–Schmitt reaction using 2-naphthol and carbon dioxide. Due to its stable aromatic framework and functional groups, the compound serves as a key intermediate in the synthesis of pigments, dyes, agrochemicals, and certain pharmaceutical compounds.

Specifications

Features

• Pigment Precursor: Acts as a key precursor for the production of BON-based pigments widely used in colorant manufacturing.
• Stable Aromatic: Contains a stable naphthalene structure that supports various chemical derivatization reactions.
• Industrial Intermediate: Widely applied as a building block in dye, agrochemical, and pharmaceutical synthesis.
• Colorant Compatibility: Easily couples with diazo compounds to produce colorants with high durability and stability.

Applications

• Pigment Manufacturing: Used to produce bright red BON pigments (such as Pigment Red 48 and Pigment Red 57:1) that exhibit strong color stability and resistance to acids and alkalis.
• Dye Production: Acts as an intermediate in azo dye synthesis through coupling reactions with diazo compounds.
• Agrochemicals: Serves as an intermediate in the preparation of certain insecticides and crop protection chemicals.
• Pharmaceutical Intermediates: Used as a building block in the synthesis of selected pharmaceutical compounds and fine chemicals.
