The occurrence of 3-(Tetramethyl-1,3,2-dioxaborolan-2-yl)-4-(trifluoromethoxy)phenol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(Tetramethyl-1,3,2-dioxaborolan-2-yl)-4-(trifluoromethoxy)phenol (CAS 1689502-03-1), molecular formula C13H16BF3O4 and molecular weight 304.07 g/mol, is a CATO reference standard with documented purity and traceability.
3-(Tetramethyl-1,3,2-dioxaborolan-2-yl)-4-(trifluoromethoxy)phenol (C13H16BF3O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.
