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.
4-(N,N-Dimethylsulfamoyl)-N-((5-((pyridin-2-ylmethyl)thio)-1,3,4-oxadiazol-2-yl)methyl)benzamide (CAS 1396748-21-2), molecular formula C18H19N5O4S2 and molecular weight 433.50 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(N,N-Dimethylsulfamoyl)-N-((5-((pyridin-2-ylmethyl)thio)-1,3,4-oxadiazol-2-yl)methyl)benzamide (C18H19N5O4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 433.50 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).
As a certified reference material (CRM), 4-(N,N-Dimethylsulfamoyl)-N-((5-((pyridin-2-ylmethyl)thio)-1,3,4-oxadiazol-2-yl)methyl)benzamide 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.
