rel-(2R,7aR)-Ethyl 2-hydroxy-5-oxohexahydro-1H-pyrrolizine-7a-carboxylate (CAS 1788873-64-2), molecular formula C10H15NO4 and molecular weight 213.23 g/mol, is a CATO reference standard with documented purity and traceability.
rel-(2R,7aR)-Ethyl 2-hydroxy-5-oxohexahydro-1H-pyrrolizine-7a-carboxylate (C10H15NO4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
