2-Naphthol, also known as beta-naphthol, is an organic compound with the formula C10H7OH. It is a white solid that is slightly soluble in water. 2-naphthol is a key intermediate in the synthesis of many dyes, pharmaceuticals, and other organic compounds. It is also used as a disinfectant and antiseptic. 2-naphthol is synthesized by the sulfonation of naphthalene, followed by alkali fusion. It is a versatile starting material for various reactions, including electrophilic aromatic substitution, diazotization, and coupling reactions. 2-Naphthol is studied extensively due to its importance in industrial processes and its potential biological activity. It has been investigated for its antimicrobial, antioxidant, and anticancer properties. However, it is also known to be a skin irritant and may cause allergic reactions. Further research is needed to understand its safety and efficacy in various applications.'
