The occurrence of N-[1-(4-Ethyl-5-mercapto-4H-[1,2,4]triazol-3-yl)-ethyl]-benzamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-[1-(4-Ethyl-5-mercapto-4H-[1,2,4]triazol-3-yl)-ethyl]-benzamide (CAS 737807-13-5), molecular formula C13H16N4OS and molecular weight 276.36 g/mol, is a CATO reference standard with documented purity and traceability.
N-[1-(4-Ethyl-5-mercapto-4H-[1,2,4]triazol-3-yl)-ethyl]-benzamide (C13H16N4OS) contains a nitrogen-containing heterocyclic scaffold, 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.
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.
