Chemical Structure
Description
(2R,5S,10aS,10bS)-Octahydro-10b-hydroxy-5-isobutyl-2-isopropyl-3,6-dioxo-8H-oxazolo[3,2-α]pyrrolo[2,1-c]pyrazine-2-carboxylic Acid (CAS 24177-07-9) is a high-purity analytical reference standard with the molecular formula C17H26N2O6 and a molecular weight of 354.40 g/mol.
Based on its molecular formula C17H26N2O6, (2R,5S,10aS,10bS)-Octahydro-10b-hydroxy-5-isobutyl-2-isopropyl-3,6-dioxo-8H-oxazolo[3,2-α]pyrrolo[2,1-c]pyrazine-2-carboxylic Acid contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 354.40 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.
