Description
(3aR,3a'R,8aS,8a'S)-2,2'-(2,3-Dihydro-1H-indene-2,2-diyl)bis(3a,8a-dihydro-8H-indeno[1,2-d]oxazole) (CAS 2757082-16-7) is a high-purity analytical reference standard with the molecular formula C29H24N2O2 and a molecular weight of 432.51 g/mol.
(3aR,3a'R,8aS,8a'S)-2,2'-(2,3-Dihydro-1H-indene-2,2-diyl)bis(3a,8a-dihydro-8H-indeno[1,2-d]oxazole) (C29H24N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (3aR,3a'R,8aS,8a'S)-2,2'-(2,3-Dihydro-1H-indene-2,2-diyl)bis(3a,8a-dihydro-8H-indeno[1,2-d]oxazole) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
