Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((4-(4-Chlorophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2,6-dichlorophenyl)acetamide.
2-((4-(4-Chlorophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2,6-dichlorophenyl)acetamide (CAS 476483-93-9) is a high-purity analytical reference standard with the molecular formula C21H14Cl3N5OS and a molecular weight of 490.79 g/mol.
2-((4-(4-Chlorophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2,6-dichlorophenyl)acetamide (C21H14Cl3N5OS) 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.
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.
