N,N-Dimethyl-4-oxo-3-(thiophen-2-yl)-1H,4H-indeno[1,2-c]pyrazole-1-carboxamide (CAS 1023536-43-7) is a high-purity analytical reference standard with the molecular formula C17H13N3O2S and a molecular weight of 323.37 g/mol.
N,N-Dimethyl-4-oxo-3-(thiophen-2-yl)-1H,4H-indeno[1,2-c]pyrazole-1-carboxamide (C17H13N3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
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.
