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 2-(4-(Benzyloxy)-2,6-dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1823170-16-6), a certified reference material (molecular formula C21H27BO3, MW 338.25 g/mol) for analytical method development and quality control.
2-(4-(Benzyloxy)-2,6-dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C21H27BO3) contains a steroid core, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
