Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 275.10 g/mol gives 6-Bromo-3-(pyridin-3-yl)-[1,2,4]triazolo[4,3-a]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Bromo-3-(pyridin-3-yl)-[1,2,4]triazolo[4,3-a]pyridine (CAS 943613-36-3), molecular formula C11H7BrN4 and molecular weight 275.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-3-(pyridin-3-yl)-[1,2,4]triazolo[4,3-a]pyridine (C11H7BrN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 6-Bromo-3-(pyridin-3-yl)-[1,2,4]triazolo[4,3-a]pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
