Chemical Structure
Description
As a certified reference material (CRM), (4aR,4bS,6aS,7S,9aS,9bR,11aR)-7-hydroxy-4a,6a,7-trimethyltetradecahydroindeno[5,4-f]chromen-2(3H)-one 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.
(4aR,4bS,6aS,7S,9aS,9bR,11aR)-7-hydroxy-4a,6a,7-trimethyltetradecahydroindeno[5,4-f]chromen-2(3H)-one (CAS 4424-45-7) is a high-purity analytical reference standard with the molecular formula C19H30O3 and a molecular weight of 306.44 g/mol.
(4aR,4bS,6aS,7S,9aS,9bR,11aR)-7-hydroxy-4a,6a,7-trimethyltetradecahydroindeno[5,4-f]chromen-2(3H)-one (C19H30O3) 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 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.
