Chemical Structure
Description
2-(4-Chlorophenoxy)-N-(5-(3-methoxyphenyl)-1,3,4-oxadiazol-2-yl)acetamide (CAS 865286-33-5) is a high-purity analytical reference standard with the molecular formula C17H14ClN3O4 and a molecular weight of 359.76 g/mol.
Structurally, 2-(4-Chlorophenoxy)-N-(5-(3-methoxyphenyl)-1,3,4-oxadiazol-2-yl)acetamide (C17H14ClN3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 359.76 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
