Chemical Structure
Description
The occurrence of 2-(6-(Benzyloxy)-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(6-(Benzyloxy)-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1204580-70-0), a certified reference material (molecular formula C19H21BF2O3, MW 346.18 g/mol) for analytical method development and quality control.
2-(6-(Benzyloxy)-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C19H21BF2O3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-(6-(Benzyloxy)-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
