Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
For professionals in the chemical, textile, and pigment industries, understanding the precise technical specifications of raw materials is fundamental to achieving optimal results. Naphthol AS-OL (CAS 135-62-6) is a critical intermediate, and detailed knowledge of its properties is essential for formulators and production managers. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier, provides high-quality Naphthol AS-OL that meets stringent industry standards.
Naphthol AS-OL is typically presented as a light beige-brown powder. Its chemical identity is well-defined, with the molecular formula C18H15NO3 and a molecular weight of 293.32 g/mol. The most critical technical specification for buyers is its assay, which for our product consistently meets or exceeds 98.5%. This high purity ensures predictable reactivity and performance, whether used as a coupling component in textile dyeing or as an intermediate in the synthesis of organic pigments.
Further key specifications include its melting point, generally around 160-164°C, which is indicative of its solid-state purity. Its solubility characteristics are also important; it is insoluble in water but slightly soluble in ethanol and sodium carbonate solutions. In sodium hydroxide solution, it exhibits a yellow color, which is a characteristic property for identification. For textile applications, its performance in coupling reactions with diazo components dictates the quality and fastness of the resulting dyed fabrics.
When you decide to buy Naphthol AS-OL, understanding these specifications allows you to confidently select a supplier that can meet your application's demands. Procurement managers and R&D scientists often require detailed technical data sheets and MSDS (Material Safety Data Sheets) to ensure compliance and safe handling. NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive documentation to support your procurement process.
