Naphthol AS-OL, identified by its CAS number 135-62-6, is a fundamental chemical intermediate that plays a pivotal role in the coloration industry. As a key component in the synthesis of a wide array of dyes and organic pigments, understanding its properties and applications is crucial for professionals in the chemical manufacturing and textile sectors. This article delves into why Naphthol AS-OL is a sought-after compound and how businesses can effectively source it from reputable manufacturers.

Chemically, Naphthol AS-OL is known as N-(2-Methoxyphenyl)-2-hydroxy-3-naphthamide. It typically presents as a beige powder with a high purity level, often specified at 99% minimum. This consistent quality makes it an ideal intermediate for applications requiring precise color formulations and reliable performance. Its primary use is as a coupling component in the azoic dyeing process, where it reacts with diazonium salts to produce insoluble azo dyes directly on the fiber. This method is favored for its ability to yield bright, wash-fast colors on substrates like cotton, silk, and synthetic fibers.

The versatility of Naphthol AS-OL extends to its use in the production of pigments for paints, plastics, and printing inks. Its structural characteristics contribute to the stability and durability of the final pigment, making it valuable in applications demanding long-lasting color. For those looking to buy Naphthol AS-OL, recognizing its significance in achieving specific color shades, such as reds, violets, and oranges when paired with appropriate diazo components, is important.

When considering manufacturers and suppliers for Naphthol AS-OL, it is beneficial to look for companies that offer comprehensive product information, including detailed specifications and safety data sheets.
