Description
Compared with other compounds in its class, the molecular weight of 457.40 g/mol gives (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3-(trifluoromethoxy)phenyl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3-(trifluoromethoxy)phenyl)acetic acid (CAS 1260609-23-1) is a high-purity analytical reference standard with the molecular formula C24H18F3NO5 and a molecular weight of 457.40 g/mol.
The molecular framework of (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3-(trifluoromethoxy)phenyl)acetic acid (C24H18F3NO5) 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 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.
