Chemical Structure
Description
5-Amino-4-iodo-2-phenylpyridazin-3(2H)-one (CAS 21235-52-9), molecular formula C10H8IN3O and molecular weight 313.09 g/mol, is a CATO reference standard with documented purity and traceability.
5-Amino-4-iodo-2-phenylpyridazin-3(2H)-one (C10H8IN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Amino-4-iodo-2-phenylpyridazin-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.
