4-Hydroxy-2-naphthalenesulfonic acid

Description:
4-Hydroxy-2-naphthalenesulfonic acid, with the CAS number 3771-14-0, is an organic compound characterized by its naphthalene structure substituted with a hydroxyl group and a sulfonic acid group. This compound typically appears as a solid, often in a crystalline form, and is soluble in water due to the presence of the sulfonic acid group, which enhances its polarity. It is known for its use as a dye intermediate and in the synthesis of various organic compounds, particularly in the textile and pharmaceutical industries. The hydroxyl group contributes to its reactivity, allowing it to participate in various chemical reactions, including sulfonation and coupling reactions. Additionally, 4-Hydroxy-2-naphthalenesulfonic acid can exhibit acidic properties due to the sulfonic acid group, making it useful in applications that require pH adjustment or as a catalyst. Safety data should be consulted for handling and storage, as with all chemical substances, to ensure proper safety measures are taken.
