Sodium phenoxide is widely used in organic synthesis as a key intermediate. It is particularly valuable in the production of pharmaceuticals, where it serves as a precursor for various drugs, including antiseptics and analgesics. In the chemical industry, it is employed in the synthesis of dyes, resins, and plasticizers, contributing to the manufacture of polymers and coatings. Additionally, sodium phenoxide is utilized in the preparation of phenolic compounds, which are essential in the development of agrochemicals like herbicides and pesticides. Its strong nucleophilic properties make it a useful reagent in Williamson ether synthesis, enabling the formation of ethers from alkyl halides. Furthermore, it plays a role in the modification of cellulose and other natural polymers, enhancing their properties for industrial applications.
