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.
N-(4-Chlorophenyl)-2-((5-(4-chlorophenyl)-4-ethyl-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 332934-44-8), molecular formula C18H16Cl2N4OS and molecular weight 407.32 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-Chlorophenyl)-2-((5-(4-chlorophenyl)-4-ethyl-4H-1,2,4-triazol-3-yl)thio)acetamide (C18H16Cl2N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
