Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 266.09 g/mol gives 4-Bromo-2-(pyridin-4-ylmethyl)pyridazin-3(2h)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-2-(pyridin-4-ylmethyl)pyridazin-3(2h)-one (CAS 2251054-36-9), molecular formula C10H8BrN3O and molecular weight 266.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-2-(pyridin-4-ylmethyl)pyridazin-3(2h)-one (C10H8BrN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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 4-Bromo-2-(pyridin-4-ylmethyl)pyridazin-3(2h)-one 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.
