Disodium 3-[(2,4-dinitrophenyl)diazenyl]-4-hydroxy-2,7-naphthalenedisulfonate (CAS: 5423-07-4) is synthesized through a multi-step process involving diazotization and coupling reactions. The key steps include the preparation of diazonium salts from 2,4-dinitrophenylhydrazine and naphthalene-3-sulfonic acid, followed by coupling to form the final product. This process typically yields about 85% pure material with a high level of selectivity.
