Chemical Structure

5,5-Diphenyloxazolidin-2-one CAS 52481-82-0 chemical structure

Description

5,5-Diphenyloxazolidin-2-one (CAS 52481-82-0) is a high-purity analytical reference standard with the molecular formula C15H13NO2 and a molecular weight of 239.27 g/mol.

5,5-Diphenyloxazolidin-2-one (C15H13NO2) contains a nitrogen-containing heterocyclic scaffold, 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 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.

As a certified reference material (CRM), 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.
