In the vibrant world of chemical manufacturing, particularly within the realm of dyes and pigments, certain intermediates stand out for their indispensability. One such compound is 1-Amino-8-hydroxynaphthalene-3,6-disulphonic acid, commonly known as H Acid. With its CAS number 90-20-0, this chemical is a cornerstone in the synthesis of a vast array of azo dyes, which are ubiquitous across industries like textiles, paints, inks, and plastics. Understanding the properties and applications of H Acid is paramount for any business involved in these sectors.

H Acid is characterized by its molecular formula C10H9NO7S2 and typically appears as a white to grey crystalline powder, with a specified purity of at least 85%. Its structure, featuring a naphthalene ring with amino, hydroxyl, and sulfonic acid groups, grants it the reactivity necessary for complex dye synthesis. The sulfonic acid groups enhance its solubility in water, making it easier to handle in various chemical processes. As a premier manufacturer and supplier of H Acid, we are dedicated to providing high-quality material that meets rigorous industry standards.

The primary application of H Acid lies in its role as a diazo component or coupling component in the production of azo dyes. Azo dyes are formed through a diazotization reaction followed by a coupling reaction. H Acid can participate in these reactions under different pH conditions, allowing for the creation of a diverse spectrum of colors. For instance, under acidic conditions, it couples ortho to the amino group, and under alkaline conditions, it couples ortho to the hydroxyl group. This versatility makes it invaluable for synthesizing complex bisazo dyes, yielding specific hues and performance characteristics.
