The molecular framework of (2S)-2-amino-3-(5-fluoro-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-1-yl)propanoic acid (S)-(-)-5-fluorowillardiine (S)-F-Willardiine (S)-alpha-Amino-5-fluoro-3,4-dihydro-2,4-dioxo-1(2H)-pyrimmidinepropanoic acid 140187-23-1 2-AMINO-3-(5-FLUORO-2,4-DIOXO-3,4-DIHYDRO-2H-PYRIMIDIN-1-YL)-PROPIONIC ACID 3-(5-fluoro-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-L-alanine 3-(5-fluorouracil-1-yl)-L-alanine 5-Fluorowillardiine CHEBI:42549 (C7H8FN3O4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.
