Chemical Structure
Description
(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3-(trifluoromethyl)phenyl)acetic acid (CAS 1260591-08-9) is a high-purity analytical reference standard with the molecular formula C24H18F3NO4 and a molecular weight of 441.40 g/mol.
(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3-(trifluoromethyl)phenyl)acetic acid (C24H18F3NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3-(trifluoromethyl)phenyl)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
