Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 173.01 g/mol gives 4-(Bromomethyl)pyridazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(Bromomethyl)pyridazine (CAS 1253790-86-1) is a high-purity analytical reference standard with the molecular formula C5H5BrN2 and a molecular weight of 173.01 g/mol.
Based on its molecular formula C5H5BrN2, 4-(Bromomethyl)pyridazine contains a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 173.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-(Bromomethyl)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.
