Chemical Structure
Description
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-(4-methoxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N,N-diethylacetamide.
CATO supplies 2-((4-(4-Chlorophenyl)-5-(4-methoxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N,N-diethylacetamide (CAS 476484-41-0), a certified reference material (molecular formula C21H23ClN4O2S, MW 430.95 g/mol) for analytical method development and quality control.
2-((4-(4-Chlorophenyl)-5-(4-methoxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N,N-diethylacetamide (C21H23ClN4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
