Description
CATO manufactures 5-Bromo-4-iodo-1-methyl-1H-pyrazole 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.
CATO supplies 5-Bromo-4-iodo-1-methyl-1H-pyrazole (CAS 2109726-53-4), a certified reference material (molecular formula C4H4BrIN2, MW 286.90 g/mol) for analytical method development and quality control.
Based on its molecular formula C4H4BrIN2, 5-Bromo-4-iodo-1-methyl-1H-pyrazole contains a nitrile group, bromine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 286.90 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
