At NINGBO INNO PHARMCHEM CO.,LTD., we are passionate about the chemistry that brings color to our world. Sodium 6-hydroxynaphthalene-2-sulfonate (CAS: 135-76-2), also known as Schaeffer's Salt, is a cornerstone chemical that enables the vibrant hues seen in countless products. Its primary function as a coupling component in the synthesis of heterocyclic monoazo dyes makes it invaluable to the global colorant industry.

The ability to create specific colors with desired properties—such as lightfastness, washfastness, and brilliance—depends heavily on the precise molecular structures of the dyes. Sodium 6-hydroxynaphthalene-2-sulfonate provides the necessary chemical scaffolding for these complex molecules. The exploration of its uses of Schaeffer's salt reveals its extensive application not just in traditional textile dyeing but also in specialized inks, coatings, and even in the synthesis of regulated colorants like FD&C Red No. 40.

The importance of this compound is further emphasized by its role in the FD&C Red No. 40 synthesis. This widely used food and cosmetic colorant requires high-purity intermediates, and Sodium 6-hydroxynaphthalene-2-sulfonate fits this requirement, demonstrating its safety and efficacy for sensitive applications. The reliability of sodium 6-hydroxynaphthalene-2-sulfonate supply is therefore critical for manufacturers in these sectors.

For researchers and developers, understanding the CAS 135-76-2 properties opens doors to new innovations. As a well-established heterocyclic monoazo dye intermediate, it serves as a benchmark for quality and a starting point for exploring novel chromophores. The consistent demand for effective and safe color solutions ensures that this compound remains a key player in chemical manufacturing.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying top-tier chemical intermediates like Sodium 6-hydroxynaphthalene-2-sulfonate, supporting industries in their pursuit of quality and innovation in color science.
