Chemical Structure
Description
The molecular framework of 2-[(3aR)-1-acetyl-3a-methyl-5-oxooctahydropyrrolo[2,3-b]pyrrol-2-yl]phenyl acetate 956253-20-6 KS-00003ONA (C17H20N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-[(3aR)-1-acetyl-3a-methyl-5-oxooctahydropyrrolo[2,3-b]pyrrol-2-yl]phenyl acetate 956253-20-6 KS-00003ONA (CAS 956253-20-6) is a high-purity analytical reference standard with the molecular formula C17H20N2O4 and a molecular weight of 316.35 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
