In the vibrant world of color, the purity and quality of raw materials are paramount. For manufacturers of organic pigments, intermediates like Naphthol AS-CA (CAS 137-52-0) play a foundational role. This compound, chemically known as N-(5-chloro-2-methoxyphenyl)-3-hydroxynaphthalene-2-carboxamide, is a key building block that enables the creation of a vast array of hues used in everything from printing inks to high-performance coatings.

Sourcing high-purity Naphthol AS-CA is not merely a transactional step; it's a strategic decision that directly impacts the final pigment's performance. Factors such as color strength, lightfastness, and chemical resistance are all influenced by the quality of this intermediate. When you are looking to buy Naphthol AS-CA, understanding its specifications and the reliability of its manufacturer is essential. Companies seeking to optimize their production processes and product quality often turn to experienced suppliers in China, where a significant portion of global chemical production takes place.

The typical form of Naphthol AS-CA is a light gray-white powder. Its chemical structure allows it to readily participate in azo coupling reactions, a fundamental process in synthesizing many organic pigments. The CAS number 137-52-0 is a universal identifier, ensuring that procurement professionals can easily source the exact material they need. Beyond its primary use in organic pigments, this intermediate also finds application in specific textile dyeing processes, particularly for cotton and other cellulosic fibers, and as a component in certain ice dye formulations.

For businesses aiming to secure a consistent and high-quality supply, exploring options from established chemical manufacturers in China is a wise strategy. These suppliers often offer competitive price points, backed by comprehensive quality control measures and an understanding of international export requirements. When inquiring about Naphthol AS-CA, always ask for detailed specifications, purity levels (ideally ≥99.0%), and information about their production capabilities. This diligence ensures that you are partnering with a reputable supplier who can meet your ongoing demands and contribute to the success of your pigment formulations.
