Description
Compared with other compounds in its class, the molecular weight of 362.81 g/mol gives 2-(4-(Benzyloxy)phenyl)-5-(4-chlorophenyl)-1,3,4-oxadiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(4-(Benzyloxy)phenyl)-5-(4-chlorophenyl)-1,3,4-oxadiazole (CAS 923029-38-3), molecular formula C21H15ClN2O2 and molecular weight 362.81 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(4-(Benzyloxy)phenyl)-5-(4-chlorophenyl)-1,3,4-oxadiazole (C21H15ClN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 362.81 g/mol, it falls into the moderately-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.
