Chemical Structure
Description
The molecular framework of (4-{[(9H-Fluoren-9-ylmethoxy)carbonyl]-amino}phenoxy)acetic acid (C23H19NO5) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
(4-{[(9H-Fluoren-9-ylmethoxy)carbonyl]-amino}phenoxy)acetic acid (CAS 1217863-10-9), molecular formula C23H19NO5 and molecular weight 389.40 g/mol, is a CATO reference standard with documented purity and traceability.
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.
