Understanding the detailed chemical properties of an intermediate is vital for formulators and manufacturers looking to optimize their products. Naphthol AS-OL (CAS 135-62-6) is a chemical compound that plays a significant role in several industrial sectors, most notably in textile dyeing and organic pigment production. As a key supplier, we provide insights into why this beige powder intermediate is so valuable.

Naphthol AS-OL, with the molecular formula C18H15NO3 and a molecular weight of 293.32, is characterized by its appearance as a beige powder and a high purity level, typically ≥99%. Its melting point ranges between 161-164 °C, indicating it is a solid at room temperature. While insoluble in water, it shows slight solubility in methanol and DMSO, and in sodium carbonate solutions. In sodium hydroxide, it appears yellow, and it can be sensitive to air over time, necessitating proper storage.

The primary application of Naphthol AS-OL is as an azoic coupling component. In the textile industry, it acts as a primer for cotton fabrics, yarns, and towels, enabling the creation of brilliant and durable colors through the azoic dyeing process. This includes its use in direct printing and discharge printing techniques. Furthermore, its chemical structure makes it an excellent intermediate for producing fast organic pigments, which are critical for the coatings, inks, and plastics industries due to their excellent color stability and resistance properties.
