Chemical Structure
Description
The molecular framework of 3-(4-Chlorophenyl)-3-{[(9H-fluoren-9-ylmethoxy)-carbonyl]amino}propanoic acid (C24H20ClNO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-(4-Chlorophenyl)-3-{[(9H-fluoren-9-ylmethoxy)-carbonyl]amino}propanoic acid (CAS 194471-87-9) is a high-purity analytical reference standard with the molecular formula C24H20ClNO4 and a molecular weight of 421.87 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
