Chemical Structure
Description
4-Bromo-3,5-diiodopyridine (CAS 1364375-66-5) is a high-purity analytical reference standard with the molecular formula C5H2BrI2N and a molecular weight of 409.79 g/mol.
4-Bromo-3,5-diiodopyridine (C5H2BrI2N) contains a nitrile group, bromine/iodine substitution. Halogen substitution raises its density and boiling point; 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 4-Bromo-3,5-diiodopyridine 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.
