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 3,4-Diiodo-1H-pyrazole (CAS 6645-70-1), a certified reference material (molecular formula C3H2I2N2, MW 319.87 g/mol) for analytical method development and quality control.
Owing to a nitrile group, iodine substitution, 3,4-Diiodo-1H-pyrazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures 3,4-Diiodo-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.
