Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Chloro-3-(4-methylphenyl)-[1,2,4]triazolo[4,3-b]pyridazine.
6-Chloro-3-(4-methylphenyl)-[1,2,4]triazolo[4,3-b]pyridazine (CAS 56383-42-7) is a high-purity analytical reference standard with the molecular formula C12H9ClN4 and a molecular weight of 244.68 g/mol.
The molecular framework of 6-Chloro-3-(4-methylphenyl)-[1,2,4]triazolo[4,3-b]pyridazine (C12H9ClN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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-Chloro-3-(4-methylphenyl)-[1,2,4]triazolo[4,3-b]pyridazine 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.
