Chemical Structure
Description
The occurrence of 6-chloro-3H-[1,2,3]triazolo[4,5-b]pyridine is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-chloro-3H-[1,2,3]triazolo[4,5-b]pyridine (CAS 408314-14-7), a certified reference material (molecular formula C5H11ClN4, MW 162.62 g/mol) for analytical method development and quality control.
The molecular framework of 6-chloro-3H-[1,2,3]triazolo[4,5-b]pyridine (C5H11ClN4) is characterized by a nitrile group, 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), 6-chloro-3H-[1,2,3]triazolo[4,5-b]pyridine 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.
