The quest for vibrant, durable, and consistent colors in textiles relies on the quality of the chemical intermediates used in the dyeing process. 3-Hydroxy-2-naphthoyl-ortho-phenetidide, commonly known as Naphthol AS-PH (CAS 92-74-0), is a fundamental component that empowers textile manufacturers to achieve these goals. As a leading manufacturer and supplier of this crucial dye intermediate from China, we understand its significance and are committed to providing the highest quality product.

The Critical Role of Naphthol AS-PH in Azoic Dyeing

Naphthol AS-PH is primarily employed as a 'primer' or 'grounding agent' in the azoic dyeing of cotton and other cellulosic fibers. In this process, the fabric is first treated with a solution containing Naphthol AS-PH. This makes the fiber receptive to a subsequent treatment with a diazo component (a diazotized amine). The reaction between the Naphthol AS-PH and the diazo component forms an insoluble azo dye molecule directly within the fiber matrix. This 'in situ' formation of the dye is what imparts exceptional fastness properties, including resistance to washing, rubbing, and light. For textile professionals looking to buy Naphthol AS-PH, understanding this mechanism highlights its importance for achieving superior color results.

Quality and Consistency: What Buyers Need to Know

When sourcing chemical intermediates like Naphthol AS-PH, consistent quality is non-negotiable. Our manufacturing process focuses on delivering a product with a purity of 99%, ensuring that each batch performs reliably in your dyeing operations. The beige powder form is easily soluble in alkaline solutions, a common requirement for its application. The chemical's stability and predictable reactivity are key benefits that our clients consistently rely on. As a trusted supplier in China, we maintain stringent quality control measures to guarantee these attributes.
