As a certified reference material (CRM), 4,5-Dinitrocatechol 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.
4,5-Dinitrocatechol (CAS 77400-30-7) is a high-purity analytical reference standard with the molecular formula C6H4N2O6 and a molecular weight of 200.11 g/mol.
The molecular framework of 4,5-Dinitrocatechol (C6H4N2O6) is characterized by a carbohydrate-derived structure, an amide group. 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.
