Chemical Structure

4-aminopyridazine-3-carboxamide CAS 20865-28-5 chemical structure

Description

The occurrence of 4-aminopyridazine-3-carboxamide is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-aminopyridazine-3-carboxamide (CAS 20865-28-5), molecular formula C5H12N4O and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.

4-aminopyridazine-3-carboxamide (C5H12N4O) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
