At NINGBO INNO PHARMCHEM CO.,LTD., we pride ourselves on providing detailed information about the chemical compounds we supply. Disperse Blue 359, a key product in our range, is an anthraquinone dye with a specific set of chemical properties that make it highly effective for various textile applications, particularly digital printing.

Disperse Blue 359, identified by the CAS number 62570-50-7, has the chemical name 1-amino-4-(ethylamino)-9,10-dihydro-9,10-dioxoanthracene-2-carbonitrile. Its molecular formula is C17H13N3O2, and its molecular weight is approximately 291.3 g/mol. These structural elements are critical to its functionality as a disperse dye. Disperse dyes are characterized by their low water solubility and their ability to dissolve or disperse in organic solvents. This makes them ideal for dyeing hydrophobic fibers such as polyester, acetate, and nylon.

The physical appearance of Disperse Blue 359 is a fine blue powder. Its solubility in water is very low (6.7μg/L at 20℃), which is typical for its class. However, it exhibits solubility in organic solvents like DMSO, which is relevant for ink formulations. The dye's pKa is predicted to be around 1.82 ± 0.20, indicating its acidic or basic properties. The predicted boiling point is 597.7±50.0 °C, and its density is approximately 1.38±0.1 g/cm³.

The primary application of Disperse Blue 359 is in digital printing technologies, including inkjet printing and heat transfer printing. Its bright color, high absorption coefficient, and excellent dyeing intensity contribute to the production of sharp, vibrant, and long-lasting prints. When used in sublimation inks, it reliably transfers onto polyester fabrics under heat, creating durable and visually appealing designs.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that the Disperse Blue 359 we supply meets stringent quality standards. This includes high purity levels (typically ≥90%), low moisture content (≤1%), and a controlled pH (6-8). These specifications are vital for ink manufacturers and textile dyers to achieve consistent and reliable results. The dye's good dyeing performance, coupled with its light and smoke fastness, makes it a preferred choice for applications requiring color stability and longevity.

By understanding the detailed chemical properties of Disperse Blue 359, manufacturers can optimize its use in their formulations and processes, ensuring the highest quality output. NINGBO INNO PHARMCHEM CO.,LTD. is your trusted partner for high-performance dyes and chemicals.
