Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-Iodopicolinic acid (CAS 73841-32-4), a certified reference material (molecular formula C6H4INO2, MW 249.01 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H4INO2, 3-Iodopicolinic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 249.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 3-Iodopicolinic acid 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.
