4-[(E)-2-Phenylethenyl]-1,2,3-thiadiazole CAS 74959-66-3

Description

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-[(E)-2-Phenylethenyl]-1,2,3-thiadiazole (CAS 74959-66-3), molecular formula C10H8N2S and molecular weight 188.25 g/mol, is a CATO reference standard with documented purity and traceability.

4-[(E)-2-Phenylethenyl]-1,2,3-thiadiazole (C10H8N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-[(E)-2-Phenylethenyl]-1,2,3-thiadiazole 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.
