Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(2-bromophenyl)acetic acid (CAS 1260593-08-5) is a high-purity analytical reference standard with the molecular formula C23H18BrNO4 and a molecular weight of 452.30 g/mol.
The molecular framework of (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(2-bromophenyl)acetic acid (C23H18BrNO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine 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 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).
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.
