3-Oxo-2,3-dihydropyridazine-4-carboxamide CAS 2125-92-0

Description

Compared with other compounds in its class, the molecular weight of 139.11 g/mol gives 3-Oxo-2,3-dihydropyridazine-4-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Oxo-2,3-dihydropyridazine-4-carboxamide (CAS 2125-92-0), molecular formula C5H5N3O2 and molecular weight 139.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-Oxo-2,3-dihydropyridazine-4-carboxamide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.11 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
