Compared with other compounds in its class, the molecular weight of 353.41 g/mol gives 2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)hexanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)hexanoic acid (CAS 144701-20-2), a certified reference material (molecular formula C21H23NO4, MW 353.41 g/mol) for analytical method development and quality control.
The molecular framework of 2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)hexanoic acid (C21H23NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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).
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 2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)hexanoic 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.
