1-(3,4-difluorophenyl)ethanol; CAS No.: 321318-21-2;1-(3,4-difluorophenyl)ethanol. PROPERTIES: 1-(3,4-difluorophenyl)ethanol is a fluorinated aromatic alcohol with molecular formula C8H7F2O. It typically exists as a colorless liquid with a mild alcoholic odor, having a boiling point around 155-160 C. The compound has limited water solubility but dissolves well in organic solvents like ether or chloroform. It exhibits moderate thermal stability but may decompose when exposed to high temperatures or strong oxidizing agents. Proper storage involves keeping it in amber glass bottles below 20 C, protected from light and moisture. APPLICATIONS: In pharmaceutical development, this compound serves as a chiral building block for synthesizing enantiomerically pure drugs. The difluorophenyl group provides structural diversity for optimizing receptor binding, while the chiral alcohol center allows for stereocontrolled synthesis (Chirality). In materials science, 1-(3,4-difluorophenyl)ethanol contributes to the creation of liquid crystalline materials, where its fluorinated aromatic core influences mesophase behavior and thermal properties (Liquid Crystals). The hydroxyl group enables further functionalization through esterification or etherification, expanding applications in polymer chemistry and surface modification (Polymer Chemistry).
