Chemical Structure
Description
The molecular framework of 2,3,5,6-Tetrachloropyridine-4-carboxaldehyde (C6HCl4NO) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine 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.
2,3,5,6-Tetrachloropyridine-4-carboxaldehyde (CAS 68054-26-2), molecular formula C6HCl4NO and molecular weight 244.89 g/mol, is a CATO reference standard with documented purity and traceability.
