Chemical Structure
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.
2-((5-Benzyl-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(2-methoxy-5-methylphenyl)acetamide (CAS 720667-78-7), molecular formula C25H24N4O2S and molecular weight 444.55 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((5-Benzyl-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(2-methoxy-5-methylphenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 444.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-((5-Benzyl-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(2-methoxy-5-methylphenyl)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.
