Chemical Structure
Description
As a certified reference material (CRM), n,n-Diethyl-7-nitrobenzo[c][1,2,5]oxadiazol-4-amine 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.
n,n-Diethyl-7-nitrobenzo[c][1,2,5]oxadiazol-4-amine (CAS 74392-01-1) is a high-purity analytical reference standard with the molecular formula C10H12N4O3 and a molecular weight of 236.23 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, n,n-Diethyl-7-nitrobenzo[c][1,2,5]oxadiazol-4-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
