5-Amino-1-cyclopentyl-1H-pyrazole-4-carboxamide CAS 666235-33-2

Description

Compared with other compounds in its class, the molecular weight of 194.23 g/mol gives 5-Amino-1-cyclopentyl-1H-pyrazole-4-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Amino-1-cyclopentyl-1H-pyrazole-4-carboxamide (CAS 666235-33-2) is a high-purity analytical reference standard with the molecular formula C9H14N4O and a molecular weight of 194.23 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Amino-1-cyclopentyl-1H-pyrazole-4-carboxamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.23 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).
