Chemical Structure
Description
As a certified reference material (CRM), Oxyfluorfen Impurity 2 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.
Oxyfluorfen Impurity 2 (CAS 50594-75-7) is a certified pharmaceutical impurity reference standard with the molecular formula C20H9Cl2F6NO4 and a molecular weight of 512.19 g/mol.
Structurally, Oxyfluorfen Impurity 2 (C20H9Cl2F6NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 512.19 g/mol, it falls into the moderately-high-molecular-weight range. 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 supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
