Chemical Structure
Description
The molecular framework of (2S,4S)-(9H-Fluoren-9-yl)methyl 4-fluoro-2-(methoxy(methyl)carbamoyl)pyrrolidine-1-carboxylate (C22H23FN2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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).
(2S,4S)-(9H-Fluoren-9-yl)methyl 4-fluoro-2-(methoxy(methyl)carbamoyl)pyrrolidine-1-carboxylate (CAS 1235447-47-8) is a high-purity analytical reference standard with the molecular formula C22H23FN2O4 and a molecular weight of 398.43 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.
