Description
Compared with other compounds in its class, the molecular weight of 167.60 g/mol gives 3-(chloromethyl)-[1,2,4]triazolo[4,3-a]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(chloromethyl)-[1,2,4]triazolo[4,3-a]pyridine (CAS 855789-56-9), a certified reference material (molecular formula C7H6ClN3, MW 167.60 g/mol) for analytical method development and quality control.
The molecular framework of 3-(chloromethyl)-[1,2,4]triazolo[4,3-a]pyridine (C7H6ClN3) is characterized by a nitrile group, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 3-(chloromethyl)-[1,2,4]triazolo[4,3-a]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.
