1-Naphthol-8-sulfonic acid

Description:
1-Naphthol-8-sulfonic acid, with the CAS number 117-22-6, is an organic compound characterized by its naphthalene structure, which features a hydroxyl group (-OH) and a sulfonic acid group (-SO3H) attached to the naphthalene ring. This compound is typically a white to light yellow crystalline solid that is soluble in water, reflecting its sulfonic acid functionality. It is known for its use as a dye intermediate and in the synthesis of various chemical compounds, particularly in the textile and pharmaceutical industries. The presence of both the hydroxyl and sulfonic acid groups contributes to its acidic properties and enhances its reactivity, making it useful in various chemical reactions, including sulfonation and coupling reactions. Additionally, 1-naphthol-8-sulfonic acid can act as a pH indicator and is involved in the production of azo dyes. Its safety profile indicates that it should be handled with care, as it may cause irritation upon contact with skin or eyes.
