Chemical Structure
Description
The occurrence of 1,2-oxazole-3-carbohydrazide is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,2-oxazole-3-carbohydrazide (CAS 62438-02-2) is a high-purity analytical reference standard with the molecular formula C4H5N3O2 and a molecular weight of 127.10 g/mol.
Based on its molecular formula C4H5N3O2, 1,2-oxazole-3-carbohydrazide 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 127.10 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).
