Solvent Yellow 56, with the CAS number 2481-94-9, is a widely utilized synthetic dye known for its brilliant yellow coloration and excellent solubility in various organic solvents. NINGBO INNO PHARMCHEM CO.,LTD. is pleased to share insights into the chemical characteristics and broad industrial applications of this key product. Understanding these properties is essential for manufacturers seeking to optimize their production processes and enhance product quality.

Chemically, Solvent Yellow 56 is an azo dye characterized by its molecular formula C16H19N3 and a molecular weight of approximately 253.34 g/mol. Its structure allows for exceptional solubility in non-polar and moderately polar organic solvents, which is the primary reason for its designation as a 'solvent dye.' This solubility is key to its performance in applications where water-based dyes would be unsuitable. For instance, in the coloration of plastics, oils, waxes, and certain fibers, the dye needs to dissolve into the matrix to impart a uniform and transparent color. Purchasing Solvent Yellow 56 from NINGBO INNO PHARMCHEM CO.,LTD. guarantees a product with consistent chemical integrity.

The primary application of Solvent Yellow 56 lies in its use as a colorant for polyester fiber pulp. However, its utility spans across numerous other industries. It is extensively used in the plastics industry for coloring materials such as polystyrene (PS), high-impact polystyrene (HIPS), rigid polyvinyl chloride (RPVC), and styrene-acrylonitrile (SAN) resins. Its good heat resistance and light fastness make it ideal for these applications, where the final products may undergo thermal processing or be exposed to light over time. Manufacturers looking to buy Solvent Yellow 56 will find it a reliable component for achieving durable and attractive plastic goods.

Beyond plastics and textiles, Solvent Yellow 56 finds applications in inks, paints, waxes, oils, and even in coloring materials like gasoline and lubricants. Its bright yellow hue and compatibility with these diverse substances underscore its versatility.
