Direct Blue 86(CAS: 1330-38-7)

Direct Blue 86 is a disperse azo dye with a molecular weight of approximately 685.9 g/mol. It has a crystalline form and a high solubility in water, making it suitable for a variety of dyeing applications. Chemically, it is relatively stable under acidic and neutral conditions but may react with strong bases. This dye exhibits excellent light and wash fastness properties.

Direct Blue 86 is synthesized through a multi-step process involving the coupling of an azoic coupling component with a disazo coupling component. The synthesis involves the use of sodium hydroxide as a catalyst. The process achieves a yield of about 85%, and the product is known for its high purity and selectivity.

Direct Blue 86 is widely used in the textile industry for dyeing cotton, wool, and synthetic fibers. It is also applied in paper and leather coating, and for coloring plastic and rubber products. The dye is particularly popular due to its excellent light and wash fastness properties, making it suitable for a variety of commercial and industrial applications.

When handling Direct Blue 86, safety goggles and gloves are essential. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate absorbents and disposed of according to local regulations. Always consult the Safety Data Sheet (SDS) for detailed handling and emergency procedures. Direct Blue 86 is not particularly hazardous, but proper PPE and safe handling practices are crucial.
