CAS 2650-18-2

Acid Blue 9

Description:

Acid Blue 9, with the CAS number 2650-18-2, is a synthetic dye belonging to the class of acid dyes, which are typically used for dyeing textiles, particularly wool and nylon. This compound is characterized by its deep blue color and high solubility in water, making it suitable for various applications in the textile industry. Acid Blue 9 is known for its excellent lightfastness and stability, which contribute to its effectiveness as a dye. Additionally, it can be used in biological staining and as a pH indicator due to its ability to change color in response to pH variations. However, like many synthetic dyes, it may pose environmental concerns, particularly regarding its biodegradability and potential toxicity to aquatic life. Safety data sheets recommend handling it with care, as it may cause irritation upon contact with skin or eyes. Overall, Acid Blue 9 is a versatile dye with significant industrial applications, but its environmental impact necessitates careful management.
