Chemical Structure
Description
The occurrence of 3-Bromo-6-chloropyridazine is closely related to a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-6-chloropyridazine (CAS 89089-18-9) is a high-purity analytical reference standard with the molecular formula C4H2BrClN2 and a molecular weight of 193.43 g/mol.
The molecular framework of 3-Bromo-6-chloropyridazine (C4H2BrClN2) is characterized by a nitrile group, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
