Description
CATO manufactures 5-Chloro-2,3-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.
5-Chloro-2,3-diiodopyridine (CAS 1261365-71-2) is a high-purity analytical reference standard with the molecular formula C5H2ClI2N and a molecular weight of 365.34 g/mol.
Owing to a nitrile group, chlorine/iodine substitution, 5-Chloro-2,3-diiodopyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 365.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
