Chemical Structure
Description
(2S,3R)-((S)-2,3,5,7a-Tetrahydro-1H-pyrrolizin-7-yl)methyl 2-hydroxy-2-isopropyl-3-methoxybutanoate (CAS 488-00-6), molecular formula C16H27NO4 and molecular weight 297.39 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H27NO4, (2S,3R)-((S)-2,3,5,7a-Tetrahydro-1H-pyrrolizin-7-yl)methyl 2-hydroxy-2-isopropyl-3-methoxybutanoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 297.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
