For professionals in the textile industry, selecting the right chemical intermediates is paramount to achieving desired coloration and performance. Naphthol AS-D, identified by its CAS number 135-61-5, stands out as a critical component, particularly for its role as a primary red primer in cotton dyeing and its utility in the synthesis of insoluble azo dyes. Understanding its properties and applications can significantly optimize your sourcing and production strategies.

Naphthol AS-D is recognized for its ecru powder appearance and its specific solubility characteristics – soluble in solvent naphtha but insoluble in water and soda solutions. This chemical profile dictates its application in the creation of dyes that exhibit excellent fastness properties. For procurement managers and R&D scientists, sourcing high-purity Naphthol AS-D from a reliable manufacturer in China is a strategic advantage. This ensures consistency in dye batches and reduces the risk of deviations in color intensity or application performance.

The primary use of Naphthol AS-D lies in its function as a coupling component for producing insoluble azo dyes on various fibers, including cotton, viscose, and certain synthetic fibers. It is also employed in direct printing and discharge printing, offering flexibility in design and application. When considering a purchase, it's essential to look for suppliers that can provide detailed specifications, such as an assay of ≥99% and a defined melting point, typically around 194°C. These technical details are crucial for formulation scientists to guarantee reproducible results.

For businesses looking to buy Naphthol AS-D, exploring partnerships with established chemical suppliers is key. These suppliers often provide not only competitive pricing but also assurance of quality control and stable supply chains. Whether you are a large-scale textile manufacturer or a specialized dye producer, ensuring a consistent supply of intermediates like Naphthol AS-D directly impacts your production efficiency and product quality. Investigate Naphthol AS-D suppliers who can offer bulk quantities and timely deliveries to meet your operational demands.

In summary, Naphthol AS-D is an indispensable chemical for the modern textile industry. By understanding its technical specifications and sourcing it from reputable manufacturers and suppliers, you can enhance the quality and vibrancy of your dyed and printed fabrics. For those seeking to purchase Naphthol AS-D, focusing on purity, application suitability, and supplier reliability will lead to the most successful outcomes in your textile coloration projects.
