Chemical Structure
Description
CATO supplies 3-Chloro-6-((5-chloropyridin-3-yl)oxy)pyridazine (CAS 175135-61-2), a certified reference material (molecular formula C9H5Cl2N3O, MW 242.06 g/mol) for analytical method development and quality control.
Structurally, 3-Chloro-6-((5-chloropyridin-3-yl)oxy)pyridazine (C9H5Cl2N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 242.06 g/mol, it falls into the medium-molecular-weight range. 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), 3-Chloro-6-((5-chloropyridin-3-yl)oxy)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.
