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 4-Bromo-2-(pyridin-2-ylmethyl)pyridazin-3(2h)-one.
4-Bromo-2-(pyridin-2-ylmethyl)pyridazin-3(2h)-one (CAS 2251054-38-1) is a high-purity analytical reference standard with the molecular formula C10H8BrN3O and a molecular weight of 266.09 g/mol.
The molecular framework of 4-Bromo-2-(pyridin-2-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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-2-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.
