Product Technical Details

Product Overview

(Difluoromethoxy)benzene, also known as difluoromethyl phenyl ether, is a valuable fluorinated aromatic compound widely employed as a building block in modern organic synthesis. With the CAS number 458-92-4 and molecular formula C7H6F2O, this colorless transparent liquid offers unique reactivity due to the electron-withdrawing yet lipophilic nature of the difluoromethoxy group. Its strategic incorporation enhances metabolic stability and membrane permeability in complex molecule design, making it indispensable in the development of active pharmaceutical ingredients (APIs) and crop protection agents.
