Chemical Structure
Description
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.
CATO supplies 4,4,5,5-Tetramethyl-2-(2-methyl-3-(trifluoromethyl)phenyl)-1,3,2-dioxaborolane (CAS 1838186-45-0), a certified reference material (molecular formula C14H18BF3O2, MW 286.10 g/mol) for analytical method development and quality control.
4,4,5,5-Tetramethyl-2-(2-methyl-3-(trifluoromethyl)phenyl)-1,3,2-dioxaborolane (C14H18BF3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
