Description
As a certified reference material (CRM), N-(2,6-Dichlorophenyl)-2-((5-((4-methoxybenzyl)thio)-1,3,4-thiadiazol-2-yl)thio)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.
N-(2,6-Dichlorophenyl)-2-((5-((4-methoxybenzyl)thio)-1,3,4-thiadiazol-2-yl)thio)acetamide (CAS 477313-75-0), molecular formula C18H15Cl2N3O2S3 and molecular weight 472.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(2,6-Dichlorophenyl)-2-((5-((4-methoxybenzyl)thio)-1,3,4-thiadiazol-2-yl)thio)acetamide (C18H15Cl2N3O2S3) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
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.
