Chemical Structure
Description
The occurrence of 2-((5-(4-Chlorophenyl)-4-ethyl-4H-1,2,4-triazol-3-yl)thio)-N,N-diphenylacetamide is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-((5-(4-Chlorophenyl)-4-ethyl-4H-1,2,4-triazol-3-yl)thio)-N,N-diphenylacetamide (CAS 332934-62-0), molecular formula C24H21ClN4OS and molecular weight 448.97 g/mol, is a CATO reference standard with documented purity and traceability.
2-((5-(4-Chlorophenyl)-4-ethyl-4H-1,2,4-triazol-3-yl)thio)-N,N-diphenylacetamide (C24H21ClN4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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).
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-((5-(4-Chlorophenyl)-4-ethyl-4H-1,2,4-triazol-3-yl)thio)-N,N-diphenylacetamide 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.
