Chemical Structure
Description
2-((5-(4-Chlorophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(naphthalen-2-yl)-N-phenylacetamide (CAS 332910-06-2), molecular formula C26H18ClN3O2S and molecular weight 471.96 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-((5-(4-Chlorophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(naphthalen-2-yl)-N-phenylacetamide (C26H18ClN3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 471.96 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.
