4-{5H,6H,7H,8H-pyrido[4,3-c]pyridazin-3-yl}pyridine CAS 2059967-44-9 chemical structure

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.

CATO supplies 4-{5H,6H,7H,8H-pyrido[4,3-c]pyridazin-3-yl}pyridine (CAS 2059967-44-9), a certified reference material (molecular formula C12H12N4, MW 212.25 g/mol) for analytical method development and quality control.

Structurally, 4-{5H,6H,7H,8H-pyrido[4,3-c]pyridazin-3-yl}pyridine (C12H12N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 212.25 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 4-{5H,6H,7H,8H-pyrido[4,3-c]pyridazin-3-yl}pyridine 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.
