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-(5-nitrofuran-2-yl)-1,3,4-oxadiazole.
2-(5-nitrofuran-2-yl)-1,3,4-oxadiazole (CAS 89488-64-2), molecular formula C6H3N3O4 and molecular weight 181.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(5-nitrofuran-2-yl)-1,3,4-oxadiazole (C6H3N3O4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(5-nitrofuran-2-yl)-1,3,4-oxadiazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
