For professionals in the textile and dye industries, understanding the nuances of key intermediates is crucial for achieving superior product quality and efficient manufacturing processes. One such vital chemical is Naphthol AS-PH, scientifically known as 3-Hydroxy-2-naphthoyl-ortho-phenetidide, with the CAS registry number 92-74-0. As a prominent manufacturer and supplier in China, we aim to shed light on why this compound is indispensable for reliable dyeing operations, especially for cotton fabrics.

The Role of Naphthol AS-PH in Textile Dyeing

Naphthol AS-PH is primarily recognized for its function as a 'grounding agent' or primer in textile dyeing. When applied to cotton yarns and fabrics, it prepares the material to readily accept and bind with subsequent dyes, particularly those from the azoic dye family. This process, often referred to as 'diazotization and coupling,' allows for the creation of vibrant, deep, and importantly, wash-fast colors directly on the fiber. The compound's chemical structure, featuring a naphthalene backbone with specific functional groups, grants it excellent affinity for cellulosic fibers like cotton, ensuring uniform application and an even dyeing base.

Key Properties for Industrial Application

From a manufacturing perspective, the specifications of Naphthol AS-PH are critical. Our product typically boasts a purity of 99%, ensuring that it meets the stringent requirements of industrial dyeing processes. It appears as a beige powder, a stable physical form that is easy to handle, measure, and incorporate into aqueous solutions used in dyeing baths. The melting point, commonly cited around 156-158°C, further indicates its chemical stability under typical processing conditions. For businesses looking to buy 3-hydroxy-2-naphthoyl-ortho-phenetidide, understanding these properties helps in selecting a reliable supplier that guarantees consistent quality batch after batch.
