Chemical Structure
Description
The occurrence of 4-(4-Bromophenyl)pyridazine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(4-Bromophenyl)pyridazine (CAS 1621468-76-5), a certified reference material (molecular formula C10H7BrN2, MW 235.08 g/mol) for analytical method development and quality control.
The molecular framework of 4-(4-Bromophenyl)pyridazine (C10H7BrN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-(4-Bromophenyl)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.
