Chemical Structure
Description
The occurrence of 5-Chloro-2,3-dimethoxypyridine hydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Chloro-2,3-dimethoxypyridine hydrochloride (CAS 1704065-35-9), molecular formula C7H8ClNO2HCl and molecular weight 210.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Chloro-2,3-dimethoxypyridine hydrochloride (C7H8ClNO2HCl) is characterized by an amide group, a carboxylic acid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
