Chemical Structure
Description
The occurrence of (S)-2-Amino-2-(2-fluorophenyl)acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-2-Amino-2-(2-fluorophenyl)acetic acid (CAS 138751-04-9), molecular formula C8H8FNO2 and molecular weight 169.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-2-Amino-2-(2-fluorophenyl)acetic acid (C8H8FNO2) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
