Chemical Structure
Description
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.
(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(5-fluoro-2-methoxyphenyl)acetic acid (CAS 2348334-86-9), molecular formula C24H20FNO5 and molecular weight 421.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(5-fluoro-2-methoxyphenyl)acetic acid (C24H20FNO5) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(5-fluoro-2-methoxyphenyl)acetic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
