1-Naphthol, also referred to as 1-hydroxy-naphthalene, is an organic compound obtained from the aromatic hydrocarbon naphthalene. This compound exists as a white crystalline solid with a subtle odor and displays high solubility in organic solvents. Scientific research extensively employs 1-naphthol across multiple applications. It serves as a reagent in the synthesis of organic compounds, encompassing polymers, and dyes. Additionally, it acts as a catalyst in the polymerization process of vinyl monomers. Notably, 1-naphthol plays a vital role as a reactant in the synthesis of 1-naphthylacetic acid and its derivatives.
