Chemical Structure
Description
(R)-4-benzyl-5,5-diphenyloxazolidin-2-one (CAS 191090-40-1) is a high-purity analytical reference standard with the molecular formula C22H19NO2 and a molecular weight of 329.39 g/mol.
(R)-4-benzyl-5,5-diphenyloxazolidin-2-one (C22H19NO2) contains a steroid core, an amide group, 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.
As a certified reference material (CRM), (R)-4-benzyl-5,5-diphenyloxazolidin-2-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.
