Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-2-Amino-4-(3,4-difluorophenyl)butanoic acid (CAS 1260596-12-0), molecular formula C10H11F2NO2 and molecular weight 215.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-2-Amino-4-(3,4-difluorophenyl)butanoic acid (C10H11F2NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
CATO manufactures (S)-2-Amino-4-(3,4-difluorophenyl)butanoic 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.
