Chemical Structure
Description
(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(2,5-dimethoxyphenyl)butanoic acid (CAS 1260601-55-5), molecular formula C27H27NO6 and molecular weight 461.51 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(2,5-dimethoxyphenyl)butanoic acid (C27H27NO6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
CATO manufactures (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(2,5-dimethoxyphenyl)butanoic 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.
