Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
1-Diazo-2-Naphthol-4-Sulfonic Acid, identified by CAS Number 887-76-3, is a multifaceted chemical intermediate with significant industrial applications. Its characteristic yellow to orange crystalline powder appearance and specific chemical properties make it valuable in several sectors, most notably in the production of dyes and in certain photochemical processes.
As a prominent manufacturer and supplier of fine chemicals in China, we are dedicated to providing detailed insights into our product offerings. 1-Diazo-2-Naphthol-4-Sulfonic Acid is synthesized to meet high standards, with a guaranteed purity of ≥90% (HPLC). Its decomposition point is around 150°C, and it is notable for being soluble in alkaline water but insoluble in most organic solvents. A critical characteristic is its photosensitivity; it decomposes under UV/visible light, necessitating storage at 0-5°C in a dark, inert atmosphere, and it has a shelf life of approximately 6 months.
The primary industrial use for this compound is as a key intermediate in the manufacturing of acid and direct dyes. The presence of a reactive diazo group allows for efficient coupling reactions, forming the chromophore of azo dyes, while the sulfonic acid group imparts the necessary water solubility, crucial for dye application in textiles and other materials. For purchasers looking to buy these intermediates, understanding these properties ensures the correct selection for their specific dye formulations.
Furthermore, its light-sensitive nature extends its utility into applications like photolithography, a process vital for creating microelectronic components. As a biochemical reagent, it also finds niche applications in scientific research. For businesses requiring this compound, sourcing from an established manufacturer like ours in China ensures quality control and competitive price points. We encourage potential clients to request a quote and explore sample options to verify product suitability.
