Chemical Structure
Description
2-[4-(4-Chlorophenyl)-2-methyl-3-oxo-1,2,4-oxadiazolidin-5-yl]-N-(pyridin-2-yl)acetamide (CAS 478033-72-6) is a high-purity analytical reference standard with the molecular formula C16H15ClN4O3 and a molecular weight of 346.77 g/mol.
Structurally, 2-[4-(4-Chlorophenyl)-2-methyl-3-oxo-1,2,4-oxadiazolidin-5-yl]-N-(pyridin-2-yl)acetamide (C16H15ClN4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 346.77 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.
As a certified reference material (CRM), 2-[4-(4-Chlorophenyl)-2-methyl-3-oxo-1,2,4-oxadiazolidin-5-yl]-N-(pyridin-2-yl)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
