(S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)-4-(tert-butoxycarbonyl)piperazine-2-carboxylic acid (CAS 244132-27-2), molecular formula C25H28N2O6 and molecular weight 452.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)-4-(tert-butoxycarbonyl)piperazine-2-carboxylic acid (C25H28N2O6) 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).
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.
