Chemical Structure
Description
3,6-Dibromopyridazine (CAS 17973-86-3) is a high-purity analytical reference standard with the molecular formula C4H8Br2N2 and a molecular weight of 243.93 g/mol.
Owing to bromine substitution, 3,6-Dibromopyridazine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.93 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), 3,6-Dibromopyridazine 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.
