Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Chlorobenzenesulfonyl)-4-(1h-imidazole-1-carbonyl)piperazine.
1-(4-Chlorobenzenesulfonyl)-4-(1h-imidazole-1-carbonyl)piperazine (CAS 852840-19-8), molecular formula C14H15ClN4O3S and molecular weight 354.81 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-Chlorobenzenesulfonyl)-4-(1h-imidazole-1-carbonyl)piperazine (C14H15ClN4O3S) contains a nitrogen-containing heterocyclic scaffold, 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. 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.
