potassium 4-ethyl-5-(2-phenylethyl)-4H-1,2,4-triazole-3-sulfonate (CAS 1864054-14-7), molecular formula C12H14N3O3SK and molecular weight 319.42 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, potassium 4-ethyl-5-(2-phenylethyl)-4H-1,2,4-triazole-3-sulfonate (C12H14N3O3SK) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 319.42 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
