Chemical Structure
Description
The occurrence of Fmoc-(S)-3-Amino-3-(2,3-dichlorophenyl)-propionic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Fmoc-(S)-3-Amino-3-(2,3-dichlorophenyl)-propionic acid (CAS 501015-35-6) is a high-purity analytical reference standard with the molecular formula C24H19Cl2NO4 and a molecular weight of 456.32 g/mol.
Fmoc-(S)-3-Amino-3-(2,3-dichlorophenyl)-propionic acid (C24H19Cl2NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Fmoc-(S)-3-Amino-3-(2,3-dichlorophenyl)-propionic 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.
