Chemical Structure
Description
As a certified reference material (CRM), 6-bromo-3-ethyl-[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.
6-bromo-3-ethyl-[1,2,4]triazolo[4,3-a]pyridine (CAS 1253789-47-7), molecular formula C8H16BrN3 and molecular weight 234.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-bromo-3-ethyl-[1,2,4]triazolo[4,3-a]pyridine (C8H16BrN3) is characterized by a nitrile group, bromine 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.
