Chemical Structure

2-[2-(3,4-Difluorophenyl)ethenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1377151-58-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[2-(3,4-Difluorophenyl)ethenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.

2-[2-(3,4-Difluorophenyl)ethenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1377151-58-0) is a high-purity analytical reference standard with the molecular formula C14H17BF2O2 and a molecular weight of 266.09 g/mol.

2-[2-(3,4-Difluorophenyl)ethenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C14H17BF2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
