Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
(2R,4S)-N-Benzyl-2-t-butyloxazolidine-4-carboxylic acid, methyl ester (CAS 145451-89-4), molecular formula C16H23NO3 and molecular weight 277.36 g/mol, is a CATO reference standard with documented purity and traceability.
(2R,4S)-N-Benzyl-2-t-butyloxazolidine-4-carboxylic acid, methyl ester (C16H23NO3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (2R,4S)-N-Benzyl-2-t-butyloxazolidine-4-carboxylic acid, methyl ester 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.
