Chemical Structure

5,5'-Bis(chloromethyl)-3,3'-bi(1,2,4-oxadiazole) CAS 3980-25-4 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 5,5'-Bis(chloromethyl)-3,3'-bi(1,2,4-oxadiazole).

5,5'-Bis(chloromethyl)-3,3'-bi(1,2,4-oxadiazole) (CAS 3980-25-4), molecular formula C6H4Cl2N4O2 and molecular weight 235.03 g/mol, is a CATO reference standard with documented purity and traceability.

5,5'-Bis(chloromethyl)-3,3'-bi(1,2,4-oxadiazole) (C6H4Cl2N4O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 5,5'-Bis(chloromethyl)-3,3'-bi(1,2,4-oxadiazole) 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.
