Import Dyestuff Intermediates 2-Naphthol Cas:135-19-3 — Buy in Bulk from Supplier in China

Dyestuff Intermediates 2-naphthol (CAS: 135-19-3) is a crystalline organic compound used primarily as a building block in the synthesis of azo dyes, pigments, and pharmaceutical intermediates. The material is supplied with a minimum purity of 98.5% as confirmed by HPLC analysis, with a melting point range of 121 to 123 degrees Celsius. It appears as white to off-white flakes and is soluble in ethanol, acetone, and alkaline solutions, but insoluble in water. This compound is stable under normal storage conditions and requires protection from prolonged exposure to light and moisture.

Typical industrial grades of 2-naphthol contain less than 0.5% moisture and less than 0.1% ash content. The compound is often processed into sodium 2-naphtholate for dye coupling reactions, and its purity directly affects chroma and yield in final dye products. Standard impurities include naphthalene and 2-nitronaphthalene, which are typically controlled below 0.05% each in commercial grades. It is not classified as a hazardous substance under GHS, but dust control is recommended during handling due to potential respiratory irritation.

This material is purchased by dye manufacturers in Asia, Europe, and North America for use in reactive and disperse dye lines, particularly for polyester and nylon textiles. Buyers also use it in the production of vitamin K3 and certain fungicides. Packaging is typically in 25kg multi-wall paper bags with inner polyethylene lining, though bulk container loads are available. Trade terms commonly offered are FOB Xiamen Port, with lead times of 10 to 15 days after order confirmation. Buyers should confirm the availability of a Certificate of Analysis and SDS prior to shipment.
