Chemical Structure
Description
The occurrence of N-((3-Phenyl-1,2,4-oxadiazol-5-yl)methyl)-2-(thiophene-3-carboxamido)oxazole-4-carboxamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-((3-Phenyl-1,2,4-oxadiazol-5-yl)methyl)-2-(thiophene-3-carboxamido)oxazole-4-carboxamide (CAS 1351596-34-3) is a high-purity analytical reference standard with the molecular formula C18H13N5O4S and a molecular weight of 395.39 g/mol.
The molecular framework of N-((3-Phenyl-1,2,4-oxadiazol-5-yl)methyl)-2-(thiophene-3-carboxamido)oxazole-4-carboxamide (C18H13N5O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
