CAS 2653-64-7: 1-[2-(1-Naphthalenyl)diazenyl]-2-naphthalenol
Description:1-[2-(1-Naphthalenyl)diazenyl]-2-naphthalenol, also known as a type of azo compound, is characterized by its distinctive azo (-N=N-) functional group, which connects two aromatic systems. This compound features two naphthalene moieties, contributing to its significant conjugated π-electron system, which enhances its stability and can impart vivid coloration, typical of azo compounds. The presence of the hydroxyl (-OH) group at the second position of one naphthalene ring adds to its chemical reactivity, making it a potential candidate for various applications, including dyes and pigments. The compound may exhibit properties such as UV-Vis absorbance due to its extended conjugation, and it can participate in various chemical reactions, including azo coupling and oxidation. Additionally, its solubility characteristics can vary depending on the solvent, influenced by the hydrophobic naphthalene rings and the hydrophilic hydroxyl group. Overall, this compound is of interest in both synthetic organic chemistry and materials science due to its structural features and potential applications.
