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.
N-(2-(4-Ethyl-6-oxopyrimidin-1(6H)-yl)ethyl)-6-(1H-pyrazol-1-yl)pyridazine-3-carboxamide (CAS 1396861-34-9) is a high-purity analytical reference standard with the molecular formula C16H17N7O2 and a molecular weight of 339.35 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, N-(2-(4-Ethyl-6-oxopyrimidin-1(6H)-yl)ethyl)-6-(1H-pyrazol-1-yl)pyridazine-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), N-(2-(4-Ethyl-6-oxopyrimidin-1(6H)-yl)ethyl)-6-(1H-pyrazol-1-yl)pyridazine-3-carboxamide 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.
