Chemical Structure
Description
2-((4-Ethyl-5-(furan-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(naphthalen-1-yl)acetamide (CAS 618413-14-2), molecular formula C20H18N4O2S and molecular weight 378.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((4-Ethyl-5-(furan-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(naphthalen-1-yl)acetamide (C20H18N4O2S) is characterized by a steroid core, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-((4-Ethyl-5-(furan-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(naphthalen-1-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.
