Chemical Structure

Opicapone Impurity 1 CAS 874518-62-4 chemical structure

Description

Opicapone Impurity 1 (C10H10O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Opicapone Impurity 1 (CAS 874518-62-4) is a certified pharmaceutical impurity reference standard with the molecular formula C10H10O5 and a molecular weight of 210.18 g/mol.

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.

As a certified reference material (CRM), Opicapone Impurity 1 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.
