CATO supplies 5-(t-Butyldimethylsilyloxy)-2-fluoro-3-(trifluoromethyl)phenylboronic acid (CAS 2096335-06-5), a certified reference material (molecular formula C13H19BF4O3Si, MW 338.18 g/mol) for analytical method development and quality control.
5-(t-Butyldimethylsilyloxy)-2-fluoro-3-(trifluoromethyl)phenylboronic acid (C13H19BF4O3Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
