Understanding the precise chemical properties and applications of intermediates is fundamental for advancements in various industries. 2-Naphthol-6,8-disulfonic acid (CAS 118-32-1), often referred to as G acid, is a significant fine chemical intermediate with a well-defined role, particularly in the synthesis of dyes. NINGBO INNO PHARMCHEM CO.,LTD., a prominent chemical supplier based in China, provides this critical compound.

The molecule of 2-Naphthol-6,8-disulfonic acid features a naphthalene core functionalized with a hydroxyl group and two sulfonic acid groups. This specific chemical configuration (C10H8O7S2) imparts valuable properties, such as enhanced water solubility due to the sulfonic acid moieties, which is crucial for many dyeing processes. The hydroxyl group at the 2-position and the sulfonic acid groups at the 6 and 8 positions are key to its reactivity as a coupling component in azo dye formation.

The primary utility of 2-Naphthol-6,8-disulfonic acid lies in its function as a coupling agent. When reacted with diazotized aromatic amines, it forms stable azo compounds that exhibit a wide range of colors. This makes it indispensable for manufacturers producing specific dyes, including C.I. Acid Orange 10 and C.I. Food Red 7, which are used in textiles and food applications, respectively. The ability to buy 2-Naphthol-6,8-disulfonic acid with guaranteed high purity, often exceeding 99.5%, from suppliers like NINGBO INNO PHARMCHEM CO.,LTD. is essential for achieving the desired coloristic and performance specifications.

Beyond dye synthesis, the chemical properties of G acid may lend themselves to other niche applications within fine chemical manufacturing. Its structure provides a platform for further chemical modifications, contributing to the diversity of products available in the specialty chemical market.
