Acid Red 97 CAS 10169-02-5

What is Acid Red 97 CAS 10169-02-5?

Acid Red 97 CAS 10169-02-5 is a complex organic azo dye formulated as a water-soluble disodium salt. Typically supplied as a red to dark red solid powder, it is manufactured through the precise diazo coupling of 2,2′-benzidinedisulfonic acid and 2-naphthol. It dissolves efficiently in water to yield a vibrant orange-red solution and is also compatible with solvents like ethanol and acetone. Characterized by its strong tinctorial strength and distinct pH-dependent color shifts, it serves as a highly reliable industrial colorant for commercial leather goods and acts as a critical component in the preparation of specialized fluorescent nanoparticles.
