Chemical Structure
Description
The occurrence of 3-Bromo-6-iodopyridazine is closely related to a nitrile group, bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-6-iodopyridazine (CAS 1266675-57-3) is a high-purity analytical reference standard with the molecular formula C4H2BrIN2 and a molecular weight of 284.88 g/mol.
Owing to a nitrile group, bromine/iodine substitution, 3-Bromo-6-iodopyridazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 3-Bromo-6-iodopyridazine 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.
