Acid Blue 9(CAS: 2650-18-2)

Acid Blue 9 (CAS: 2650-18-2) is a water-soluble azo dye with a deep blue color. It has a molecular weight of approximately 662.3 g/mol. The dye is highly stable to light and heat, and it is moderately soluble in water. It shows good reactivity with cellulose fibers and has a high reactive potential with protein fibers. Acid Blue 9 is often used in the textile and paper industries due to its colorfastness and stability.

Acid Blue 9 (CAS: 2650-18-2) is synthesized through a multi-step process involving the coupling of a monoazo coupling component with a disazo coupling component. The reaction is usually conducted under acidic conditions with a catalyst such as sulfuric acid. The synthetic process yields a product with a high degree of purity and selectivity, making it suitable for commercial applications in the dye industry.

Acid Blue 9 (CAS: 2650-18-2) is widely used in the textile and paper industries for dyeing and finishing processes. It is also utilized in the plastics and pigments industries for coloring applications. Additionally, it finds use in the pharmaceutical industry for coloring tablets and capsules. Its stability and colorfastness make it a preferred choice in these sectors.

When handling Acid Blue 9 (CAS: 2650-18-2), it is essential to use personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. Ensure that the work is conducted in a well-ventilated area or a fume hood to prevent inhalation of dust or particulates. Spills should be cleaned up using appropriate absorbent materials, and proper disposal procedures should be followed. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
