Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(2-Chloro-4-nitrophenyl)-1,3,4-oxadiazol-2(3H)-one.
CATO supplies 5-(2-Chloro-4-nitrophenyl)-1,3,4-oxadiazol-2(3H)-one (CAS 1216686-76-8), a certified reference material (molecular formula C8H4ClN3O4, MW 241.59 g/mol) for analytical method development and quality control.
5-(2-Chloro-4-nitrophenyl)-1,3,4-oxadiazol-2(3H)-one (C8H4ClN3O4) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
CATO manufactures 5-(2-Chloro-4-nitrophenyl)-1,3,4-oxadiazol-2(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
