Chemical Structure
Description
1-(((9H-fluoren-9-yl)methoxy)carbonyl)-3-(tert-butoxycarbonyl)imidazolidine-2-carboxylic acid (CAS 207129-12-2), molecular formula C24H26N2O6 and molecular weight 438.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(((9H-fluoren-9-yl)methoxy)carbonyl)-3-(tert-butoxycarbonyl)imidazolidine-2-carboxylic acid (C24H26N2O6) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
