Chemical Structure
Description
The occurrence of 4-Ethyl-4-phenyloxazolidin-2-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Ethyl-4-phenyloxazolidin-2-one (CAS 99855-07-9), molecular formula C11H13NO2 and molecular weight 191.23 g/mol, is a CATO reference standard with documented purity and traceability.
4-Ethyl-4-phenyloxazolidin-2-one (C11H13NO2) contains an amino-acid-derived structure, 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), 4-Ethyl-4-phenyloxazolidin-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.
