Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-3-iodo-2H-pyrazolo[3,4-c]pyridine.
CATO supplies 4-Bromo-3-iodo-2H-pyrazolo[3,4-c]pyridine (CAS 1357946-92-9), a certified reference material (molecular formula C6H3BrIN3, MW 323.92 g/mol) for analytical method development and quality control.
Owing to a nitrile group, bromine/iodine substitution, an aromatic ring system, 4-Bromo-3-iodo-2H-pyrazolo[3,4-c]pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.92 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.
As a certified reference material (CRM), 4-Bromo-3-iodo-2H-pyrazolo[3,4-c]pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
