Chemical Structure
Description
The occurrence of (3AS,4R,6R,7aR)-2-benzyl-3a,5,5-trimethylhexahydro-4,6-methanobenzo[d][1,3,2]dioxaborole is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (3AS,4R,6R,7aR)-2-benzyl-3a,5,5-trimethylhexahydro-4,6-methanobenzo[d][1,3,2]dioxaborole (CAS 78922-83-5), a certified reference material (molecular formula C17H23BO2, MW 270.17 g/mol) for analytical method development and quality control.
(3AS,4R,6R,7aR)-2-benzyl-3a,5,5-trimethylhexahydro-4,6-methanobenzo[d][1,3,2]dioxaborole (C17H23BO2) 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 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.
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.
