2,2'-((4-Cyanoisothiazole-3,5-diyl)bis(sulfanediyl))bis(N-(5-ethyl-1,3,4-thiadiazol-2-yl)acetamide) (CAS 327168-06-9) is a high-purity analytical reference standard with the molecular formula C16H16N8O2S5 and a molecular weight of 512.68 g/mol.
The molecular framework of 2,2'-((4-Cyanoisothiazole-3,5-diyl)bis(sulfanediyl))bis(N-(5-ethyl-1,3,4-thiadiazol-2-yl)acetamide) (C16H16N8O2S5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 2,2'-((4-Cyanoisothiazole-3,5-diyl)bis(sulfanediyl))bis(N-(5-ethyl-1,3,4-thiadiazol-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.
