2-((4-Ethyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-mesitylacetamide CAS 556804-75-2

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

2-((4-Ethyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-mesitylacetamide (CAS 556804-75-2), molecular formula C19H22N4OS2 and molecular weight 386.53 g/mol, is a CATO reference standard with documented purity and traceability.

2-((4-Ethyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-mesitylacetamide (C19H22N4OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
