2 3 5 6-Tetrafluorobenzyl alcohol, MF: C₇H₄F₄O MW: 180.10, appears as white crystalline solids. Its molecular structure features four hydrogen atoms on the benzene ring replaced by fluorine atoms (at positions 2,3,5,6), with a hydroxyl group (-CH₂OH) attached at the benzyl position (1-position). (-CH₂OH). As a fluorinated aromatic alcohol derivative bearing a benzyl hydroxyl group, tetrafluorobenzyl alcohol exhibits typical alcohol properties, undergoing esterification and substitution reactions. The fluorine atoms on the benzene ring enhance the reactivity of the benzylic hydroxyl group, making it more readily participate in nucleophilic substitution reactions.
