Chemical Structure

(S)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,5-difluorophenyl)propanoic acid CAS 1260593-16-5 chemical structure

Description

The occurrence of (S)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,5-difluorophenyl)propanoic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,5-difluorophenyl)propanoic acid (CAS 1260593-16-5), a certified reference material (molecular formula C24H19F2NO4, MW 423.41 g/mol) for analytical method development and quality control.

The molecular framework of (S)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,5-difluorophenyl)propanoic acid (C24H19F2NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
