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 5-Bromo-2-(pyridin-2-ylmethyl)pyridazin-3(2h)-one.
5-Bromo-2-(pyridin-2-ylmethyl)pyridazin-3(2h)-one (CAS 2251054-23-4), molecular formula C10H8BrN3O and molecular weight 266.09 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-2-(pyridin-2-ylmethyl)pyridazin-3(2h)-one (C10H8BrN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 5-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.
