Chemical Structure
Description
The molecular framework of N-(2-chloropyridin-3-yl)isobutyramide (C9H11ClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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 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).
N-(2-chloropyridin-3-yl)isobutyramide (CAS 547705-74-8) is a high-purity analytical reference standard with the molecular formula C9H11ClN2O and a molecular weight of 198.65 g/mol.
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.
