2-{4-[(4-Fluorophenyl)carbonyl]phenyl}-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 2377607-18-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 326.17 g/mol gives 2-{4-[(4-Fluorophenyl)carbonyl]phenyl}-4,4,5,5-tetramethyl-1,3,2-dioxaborolane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-{4-[(4-Fluorophenyl)carbonyl]phenyl}-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2377607-18-4), molecular formula C19H20BFO3 and molecular weight 326.17 g/mol, is a CATO reference standard with documented purity and traceability.

2-{4-[(4-Fluorophenyl)carbonyl]phenyl}-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C19H20BFO3) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
