CATO supplies 4-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-1-(3-trifluoromethyl-benzyl)-1H-pyrazole (CAS 1415825-08-9), a certified reference material (molecular formula C17H20BF3N2O2, MW 352.16 g/mol) for analytical method development and quality control.
4-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-1-(3-trifluoromethyl-benzyl)-1H-pyrazole (C17H20BF3N2O2) contains a steroid core, an amide 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
