3-Hydroxy-N-(2-methoxyphenyl)-2-naphthamide

Product Overview

3-Hydroxy-N-(2-methoxyphenyl)-2-naphthamide, widely recognized in the industry as Naphthol AS-OL, is a premium azoic coupling component essential for the production of high-performance dyes and organic pigments. This specialized chemical intermediate serves as a foundational building block for textile manufacturers and pigment formulators seeking superior colorfastness and vibrancy. Our facility produces this compound under strict quality control protocols to ensure batch-to-batch consistency, meeting the rigorous demands of global industrial supply chains.

As a key member of the Naphthol AS series, this compound exhibits excellent coupling properties with various diazonium salts. The resulting azoic colors are renowned for their brilliance and durability on cellulosic fibers. We prioritize industrial purity standards, delivering a product that minimizes impurities which could otherwise affect shade consistency or dyeing efficiency.

Technical Specifications

Industrial Applications

This coupling component is primarily utilized in the dyeing and printing of cotton and viscose fibers. It enables the creation of insoluble azo dyes directly on the fiber, resulting in exceptional wash and rub fastness. Beyond textiles, it is a critical raw material for manufacturing fast pigment yellow, fast sulfonate, fast amine, and various organic pigments used in inks, coatings, and plastics. Manufacturers rely on this intermediate for its stability during the coupling process and its ability to produce sharp, clean shades.

Quality Assurance and Storage

We understand that consistency is vital for industrial processing. Each batch undergoes comprehensive analysis, including HPLC purity testing and melting point verification, before release. A Certificate of Analysis (COA) is provided with every shipment to verify compliance with specified parameters. For optimal stability, the product should be stored in a tightly closed container within a cool, dry, and well-ventilated area. It is classified for storage in flammables-areas away from incompatible substances to maintain safety and integrity.
