Chemical Structure
Description
N-(3,5-Dimethylphenyl)-2-((5-((naphthalen-1-ylmethyl)thio)-1,3,4-thiadiazol-2-yl)thio)acetamide (CAS 476484-09-0), molecular formula C23H21N3OS3 and molecular weight 451.63 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(3,5-Dimethylphenyl)-2-((5-((naphthalen-1-ylmethyl)thio)-1,3,4-thiadiazol-2-yl)thio)acetamide (C23H21N3OS3) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
As a certified reference material (CRM), N-(3,5-Dimethylphenyl)-2-((5-((naphthalen-1-ylmethyl)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.
