Chemical Structure
Description
The occurrence of 8-Bromopyrido[3,4-d]pyridazine is closely related to a nitrile group, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
8-Bromopyrido[3,4-d]pyridazine (CAS 40511-78-2) is a high-purity analytical reference standard with the molecular formula C7H4BrN3 and a molecular weight of 210.03 g/mol.
Owing to a nitrile group, bromine substitution, an aromatic ring system, 8-Bromopyrido[3,4-d]pyridazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 8-Bromopyrido[3,4-d]pyridazine 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.
