Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 224.13 g/mol gives 5,6-Dinitro-1,3-dihydro-benzoimidazol-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5,6-Dinitro-1,3-dihydro-benzoimidazol-2-one (CAS 3705-86-0), a certified reference material (molecular formula C7H4N4O5, MW 224.13 g/mol) for analytical method development and quality control.
The molecular framework of 5,6-Dinitro-1,3-dihydro-benzoimidazol-2-one (C7H4N4O5) 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), 5,6-Dinitro-1,3-dihydro-benzoimidazol-2-one 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.
