Chemical Structure
Description
CATO supplies (R)-7’-[(R)-Hydroxy(phenyl)methyl]-2,2’,3,3’-tetrahydro-1,1’-spirobi[inden]-7-ol (CAS 1451057-23-0), a certified reference material (molecular formula C24H22O2, MW 342.43 g/mol) for analytical method development and quality control.
(R)-7’-[(R)-Hydroxy(phenyl)methyl]-2,2’,3,3’-tetrahydro-1,1’-spirobi[inden]-7-ol (C24H22O2) 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.
