For professionals in the chemical industry, understanding the foundational chemistry of a product is key to optimizing its use and identifying new applications. Disperse Violet 26 (CAS 6408-72-6) is a prominent example of an anthraquinone-based dye that plays a crucial role in various industrial sectors. Its specific chemical structure dictates its unique properties, making it a valuable asset for manufacturers seeking high-performance coloration solutions.

At its core, Disperse Violet 26 is derived from the anthraquinone chemical family. This structural foundation is significant because anthraquinone dyes are known for their excellent stability, particularly their resistance to light and heat. This inherent stability is directly translated into the dye's superior performance characteristics. When you consider purchasing Disperse Violet 26, understanding this chemical basis helps explain why it offers such dependable results in challenging applications.

The molecular formula, C26H18N2O4, and a molecular weight of 422.43 g/mol, provide specific details about its composition. The presence of amino and phenoxy groups attached to the anthraquinone core contributes to its dyeing properties and affinity for certain substrates. This molecular architecture is precisely what allows it to function effectively as a disperse dye – meaning it is sparingly soluble in water and applied from a fine aqueous dispersion to hydrophobic fibers like polyester.

One of the most sought-after properties of Disperse Violet 26 is its high purity, typically exceeding 99.0%. This level of purity is critical for achieving consistent color shades and predictable performance. Impurities can lead to color variations, reduced color strength, and diminished fastness properties, making it essential for buyers to source from a reputable manufacturer who can guarantee this assay. When you buy this dye, ensure the supplier provides detailed specifications confirming this high purity.

The physical appearance of Disperse Violet 26 as a reddish-brown powder is another observable characteristic. This form is typical for disperse dyes, facilitating their dispersion in the dyebath. Its solubility in alcohol and other organic solvents, while being sparingly soluble in water, is key to its application method.

The applications of Disperse Violet 26 are a direct consequence of its chemical properties. Its excellent heat resistance, a hallmark of anthraquinone dyes, makes it ideal for coloring plastics that undergo high-temperature processing. Materials like PS, ABS, PMMA, PC, and PET can be effectively colored without the dye degrading. Similarly, its good light fastness ensures that colored polyester fibers and fabrics maintain their vibrancy over time, resisting fading from UV exposure.

For professionals involved in textile dyeing and plastic manufacturing, understanding the chemistry of Disperse Violet 26 empowers informed decision-making. Knowing its anthraquinone basis explains its durability, while its purity specifications dictate its reliability. When seeking to purchase this dye, engaging with knowledgeable suppliers who can articulate these chemical advantages and offer competitive pricing will lead to the most effective and cost-efficient procurement.
