Ethyl 3-((4-nitro-1h-pyrazol-1-yl)methyl)-1,2,4-oxadiazole-5-carboxylate CAS 956263-73-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-((4-nitro-1h-pyrazol-1-yl)methyl)-1,2,4-oxadiazole-5-carboxylate.

Ethyl 3-((4-nitro-1h-pyrazol-1-yl)methyl)-1,2,4-oxadiazole-5-carboxylate (CAS 956263-73-3), molecular formula C9H9N5O5 and molecular weight 267.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H9N5O5, Ethyl 3-((4-nitro-1h-pyrazol-1-yl)methyl)-1,2,4-oxadiazole-5-carboxylate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 267.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
