The world of color relies heavily on specialized chemical intermediates, and 3-Hydroxy-2-naphthoyl-ortho-phenetidide (CAS 92-74-0), also known as Naphthol AS-PH, stands out as a cornerstone for many dyeing and pigment applications. As a dedicated supplier of fine chemicals, we believe in empowering our clients with in-depth knowledge about the materials they source. This article explores the chemical characteristics and diverse applications of Naphthol AS-PH, highlighting why it's a sought-after product for manufacturers globally.

Chemical Structure and Properties

Naphthol AS-PH is an organic compound with the molecular formula C19H17NO3 and a molecular weight of approximately 307.34 g/mol. Its structure is characterized by a naphthalene ring system substituted with a hydroxyl group at the 3-position and a carboxamide linkage to an ethoxyphenyl group. This arrangement is critical for its function as an azoic coupling component. The hydroxyl group and the conjugated aromatic systems contribute to its coloristic properties when it undergoes the azo coupling reaction. Typically appearing as a beige powder with a purity of around 99%, it offers good solubility in alkaline solutions and glacial acetic acid, common solvents in dye synthesis and application.

Applications in the Dye and Pigment Industry

The primary application of Naphthol AS-PH is as an intermediate in the synthesis of dyes and pigments. It is widely used as a primer or grounding agent for cotton fabrics, enhancing dye uptake and fixation, particularly for azoic dyes. This leads to excellent color fastness to washing and light. Beyond textiles, Naphthol AS-PH is also utilized in the production of organic pigments that are incorporated into paints, inks, and plastics, contributing to vibrant and stable coloration. When you buy Naphthol AS-PH, you are investing in a versatile compound that forms the basis of many brilliant shades.
