Tafluprost Impurity N76 CAS 2065-23-8 chemical structure

Description

As a certified reference material (CRM), Tafluprost Impurity N76 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.

Tafluprost Impurity N76 (CAS 2065-23-8) is a certified pharmaceutical impurity reference standard with the molecular formula C9H10O3 and a molecular weight of 166.17 g/mol.

Tafluprost Impurity N76 (C9H10O3) 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 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.
