Chemical Structure
Description
CATO supplies (3AS,4R,6R,7aR)-3a,5,5-trimethyl-2-phenylhexahydro-4,6-methanobenzo[d][1,3,2]dioxaborole (CAS 76110-78-6), a certified reference material (molecular formula C16H21BO2, MW 256.15 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (3AS,4R,6R,7aR)-3a,5,5-trimethyl-2-phenylhexahydro-4,6-methanobenzo[d][1,3,2]dioxaborole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
