N-(3-chlorophenyl)-6-oxo-1-phenyl-4-(propylthio)-1,6-dihydropyridazine-3-carboxamide CAS 339031-93-5

Description

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.

N-(3-chlorophenyl)-6-oxo-1-phenyl-4-(propylthio)-1,6-dihydropyridazine-3-carboxamide (CAS 339031-93-5) is a high-purity analytical reference standard with the molecular formula C20H18ClN3O2S and a molecular weight of 399.89 g/mol.

N-(3-chlorophenyl)-6-oxo-1-phenyl-4-(propylthio)-1,6-dihydropyridazine-3-carboxamide (C20H18ClN3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
