Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 197.03 g/mol gives 5-Chloro-3-fluoro-2-methylaminopyridine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Chloro-3-fluoro-2-methylaminopyridine hydrochloride (CAS 1704064-97-0), molecular formula C6H6ClFN2HCl and molecular weight 197.03 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Chloro-3-fluoro-2-methylaminopyridine hydrochloride (C6H6ClFN2HCl) is characterized by a nitrile group, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-Chloro-3-fluoro-2-methylaminopyridine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
