Description
CATO manufactures Dibromotetrakis(pyridine)nickel 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.
Dibromotetrakis(pyridine)nickel (CAS 14129-04-5), molecular formula C20H20Br2N4Ni and molecular weight 534.90 g/mol, is a CATO reference standard with documented purity and traceability.
Dibromotetrakis(pyridine)nickel (C20H20Br2N4Ni) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
