2-(2-Chlorophenyl)imidazo[1,2-b]pyridazine-3-carboxylic acid CAS 1956331-42-2

Description

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.

2-(2-Chlorophenyl)imidazo[1,2-b]pyridazine-3-carboxylic acid (CAS 1956331-42-2) is a high-purity analytical reference standard with the molecular formula C13H8ClN3O2 and a molecular weight of 273.67 g/mol.

The molecular framework of 2-(2-Chlorophenyl)imidazo[1,2-b]pyridazine-3-carboxylic acid (C13H8ClN3O2) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), 2-(2-Chlorophenyl)imidazo[1,2-b]pyridazine-3-carboxylic 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.
