Acid Blue 7

Description:

Acid Blue 7, also known as Acid Blue 25 or by its chemical name, Disodium 4-amino-5-hydroxy-3-(2-sulfonatophenylazo) naphthalene-1-sulfonate, is a synthetic dye belonging to the azo dye class. It is characterized by its vibrant blue color and is commonly used in various applications, including textiles, food, and cosmetics. The dye is water-soluble, which enhances its applicability in aqueous solutions. Acid Blue 7 exhibits good lightfastness and stability, making it suitable for use in products that require durability against fading. However, like many azo dyes, it may raise environmental and health concerns due to potential toxicity and allergenic properties. Its chemical structure includes sulfonate groups, which contribute to its solubility and reactivity. In terms of safety, it is essential to handle Acid Blue 7 with care, following appropriate guidelines to minimize exposure and environmental impact. Overall, Acid Blue 7 is a versatile dye with significant industrial relevance, but its use must be managed responsibly.

Patent Blue A

CAS: 3486-30-4

Patent Blue A is a blue pigment with a deep color, which is used in detergent compositions. This pigment has a hydroxyl group on the surface and can be synthesized by reacting zirconium oxide with quinoline derivatives in an acidic solution. Patent Blue A has been shown to have good dispersibility and stability. It is insoluble in water but soluble in organic solvents such as chloroform and benzene. It also shows good radiation resistance and thermodynamic stability, making it suitable for use in medical devices or other products exposed to radiation, such as blood culture plates.
