Chemical Structure
Description
(S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(2-chlorobenzyl)propanoic acid (CAS 1260591-38-5), molecular formula C25H22ClNO4 and molecular weight 435.90 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(2-chlorobenzyl)propanoic acid (C25H22ClNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures (S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(2-chlorobenzyl)propanoic 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.
