NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing clarity on the chemical intricacies of Disperse Violet 28 (CAS 81-42-5), a significant anthraquinone dye. Understanding the chemical properties of this compound is fundamental to appreciating its broad industrial applications, from vibrant textile coloration to its use in coloring various resins. The molecular formula, C14H8Cl2N2O2, and its structure as 1,4-diamino-2,3-dichloroanthracene-9,10-dione, are central to its performance characteristics.

The physical form of Disperse Violet 28 is typically a dark purple powder. Its solubility profile is noteworthy: it readily dissolves in organic solvents like acetone, ethanol, and benzene, but remains insoluble in water. This characteristic is precisely what classifies it as a disperse dye, meaning it requires dispersing agents for effective application in aqueous dyeing baths. The chemical stability of Disperse Violet 28 is also a key factor; it maintains its color integrity across a pH range of 3 to 9 and shows good resistance to heat and light. The CAS 81-42-5 dye properties highlight its robustness.

Industrially, Disperse Violet 28 is highly valued for its contribution to creating bright, reddish-purple shades, particularly on polyester fibers. Its excellent lightfastness and sublimation fastness are critical for applications where color durability is paramount. Manufacturers seeking to buy Disperse Violet 28 for textile purposes can expect consistent results due to its high purity, often exceeding 99.0%. The dye also serves as an important intermediate in the synthesis of other dyes, such as Disperse Cyanine HBF and Disperse Cyanine S-GL, underscoring its role in the broader chemical manufacturing landscape.

The application of Disperse Violet 28 in resin coloring further broadens its industrial significance. Its ability to color various plastic resins efficiently and provide a stable, vibrant hue makes it a valuable component in the manufacturing of colored plastic goods. NINGBO INNO PHARMCHEM CO.,LTD. ensures that the Disperse Violet 28 supplied adheres to high standards, supporting manufacturers in achieving their desired product aesthetics and performance. Exploring the detailed Disperse Violet 28 dye for polyester and other applications reveals its true versatility.
