Chemical Structure
Description
CATO supplies 4,4,5,5-tetramethyl-2-(3-(trifluoromethoxy)phenyl)-1,3,2-dioxaborolane (CAS 262376-31-8), a certified reference material (molecular formula C13H22BF3O3, MW 294.12 g/mol) for analytical method development and quality control.
4,4,5,5-tetramethyl-2-(3-(trifluoromethoxy)phenyl)-1,3,2-dioxaborolane (C13H22BF3O3) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
