Chemical Structure
Description
The occurrence of 4-Aminopyridazine-3-carbonitrile is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Aminopyridazine-3-carbonitrile (CAS 20865-26-3), a certified reference material (molecular formula C5H4N4, MW 120.11 g/mol) for analytical method development and quality control.
Structurally, 4-Aminopyridazine-3-carbonitrile (C5H4N4) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 120.11 g/mol, it falls into the low-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.
CATO manufactures 4-Aminopyridazine-3-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
