potassium 4-methyl-5-(2-phenylethyl)-4H-1,2,4-triazole-3-sulfonate (CAS 1864063-19-3), molecular formula C11H12N3O3SK and molecular weight 305.39 g/mol, is a CATO reference standard with documented purity and traceability.
potassium 4-methyl-5-(2-phenylethyl)-4H-1,2,4-triazole-3-sulfonate (C11H12N3O3SK) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
