Chemical Structure
Description
4-Benzyl-7-nitrobenzo[c][1,2,5]oxadiazole (CAS 143909-00-6), molecular formula C13H9N3O3 and molecular weight 255.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Benzyl-7-nitrobenzo[c][1,2,5]oxadiazole (C13H9N3O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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), 4-Benzyl-7-nitrobenzo[c][1,2,5]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.
