Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2-Chloro-4-nitrophenyl)-2-((5-(o-tolyl)-1,3,4-oxadiazol-2-yl)thio)acetamide.
N-(2-Chloro-4-nitrophenyl)-2-((5-(o-tolyl)-1,3,4-oxadiazol-2-yl)thio)acetamide (CAS 332357-70-7) is a high-purity analytical reference standard with the molecular formula C17H13ClN4O4S and a molecular weight of 404.83 g/mol.
N-(2-Chloro-4-nitrophenyl)-2-((5-(o-tolyl)-1,3,4-oxadiazol-2-yl)thio)acetamide (C17H13ClN4O4S) contains a flavonoid 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. 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.
