For procurement managers, R&D scientists, and product formulators in the chemical industry, a deep understanding of key intermediates is essential. Naphthol AS-ITR, identified by CAS 92-72-8, is one such compound that warrants close attention due to its significant role in various manufacturing processes, particularly in the realm of dyes and pigments. Known chemically as 2-Naphthalenecarboxamide, N-(5-chloro-2,4-dimethoxyphenyl)-3-hydroxy-, this intermediate is valued for its contribution to color vibrancy and stability.

The chemical profile of Naphthol AS-ITR is characterized by its molecular formula C19H16ClNO4 and a molecular weight of approximately 357.79 g/mol. Crucially, its purity level is a key specification for end-users. Manufacturers typically aim for a high purity, often around 99%, to ensure predictable and optimal performance in their applications. The physical appearance is generally described as a white to amber powder or crystal, and it is noted for its solubility in solvents like Dimethylformamide, while being insoluble in water.

The primary applications for Naphthol AS-ITR revolve around its function as an azoic coupling component and a dye intermediate. In textile dyeing, it is used to create a range of bright and fast colors on various fibers, including cotton. Its ability to form insoluble azo dyes directly on the fabric is a cornerstone of the azoic dyeing technique, prized for its color intensity and wash fastness. Furthermore, it finds use in the manufacturing of pigments, contributing essential properties to paints, inks, and plastics where color performance is critical.

When considering the purchase of Naphthol AS-ITR, procurement professionals should focus on identifying reliable suppliers who can provide detailed specifications, certificates of analysis, and consistent product quality. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier of fine chemicals, offers this crucial intermediate. By understanding the technical specifications and application benefits, businesses can make informed decisions to source CAS 92-72-8, ensuring their production processes are supported by high-quality raw materials.
