Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-Ethyl-5-(4-methyl-2-phenyl-1,3-thiazol-5-yl)-4H-1,2,4-triazol-3-ylhydrosulfide (CAS 219860-19-2), molecular formula C14H14N4S2 and molecular weight 302.42 g/mol, is a CATO reference standard with documented purity and traceability.

4-Ethyl-5-(4-methyl-2-phenyl-1,3-thiazol-5-yl)-4H-1,2,4-triazol-3-ylhydrosulfide (C14H14N4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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.
