Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 852.95 g/mol gives 5-Styryl-1,3,4-oxadiazol-2(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Styryl-1,3,4-oxadiazol-2(3H)-one (CAS 34547-10-9), molecular formula C14H8I4O4C4H11NO2 and molecular weight 852.95 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Styryl-1,3,4-oxadiazol-2(3H)-one (C14H8I4O4C4H11NO2) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 852.95 g/mol, it falls into the high-molecular-weight range. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
