For professionals in the textile industry, understanding the core components that deliver vibrant and lasting colors is paramount. Naphthol AS-D, scientifically known as 3-hydroxy-N-(2-methylphenyl)-2-naphthalenecarboxamide, with CAS number 135-61-5, stands out as a crucial intermediate in the creation of azo dyes. Its primary application lies in the dyeing of cotton yarns and fabrics, where it acts as an essential coupling component to achieve a wide spectrum of shades.
