2-({[2-(Ethylthio)-3-pyridyl]carbonyl}-amino)-4-(methylthio)butanoic acid CAS 175201-66-8

Description

The molecular framework of 2-({[2-(Ethylthio)-3-pyridyl]carbonyl}-amino)-4-(methylthio)butanoic acid (C13H18N2O3S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 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).
