Chemical Structure

4-(2-Aminoethyl)-3-(4-(dimethylamino)phenyl)-5-oxo-2,5-dihydro-1H-pyrazole-1-carboxamide sulfate CAS 1177351-77-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 387.41 g/mol gives 4-(2-Aminoethyl)-3-(4-(dimethylamino)phenyl)-5-oxo-2,5-dihydro-1H-pyrazole-1-carboxamide sulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(2-Aminoethyl)-3-(4-(dimethylamino)phenyl)-5-oxo-2,5-dihydro-1H-pyrazole-1-carboxamide sulfate (CAS 1177351-77-7), molecular formula C14H19N5O2H2O4S and molecular weight 387.41 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-(2-Aminoethyl)-3-(4-(dimethylamino)phenyl)-5-oxo-2,5-dihydro-1H-pyrazole-1-carboxamide sulfate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 387.41 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.
