Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 234.64 g/mol gives 4-(6-Chloropyridazin-3-yl)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(6-Chloropyridazin-3-yl)benzoic acid (CAS 845827-17-0), a certified reference material (molecular formula C11H7ClN2O2, MW 234.64 g/mol) for analytical method development and quality control.
The molecular framework of 4-(6-Chloropyridazin-3-yl)benzoic acid (C11H7ClN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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 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-(6-Chloropyridazin-3-yl)benzoic acid 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.
