Chemical Structure

Ketoprofen Impurity 116 CAS 1777830-06-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 357.40 g/mol gives Ketoprofen Impurity 116 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ketoprofen Impurity 116 (CAS 1777830-06-4) is a certified pharmaceutical impurity reference standard with the molecular formula C20H23NO5 and a molecular weight of 357.40 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Ketoprofen Impurity 116 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 357.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Ketoprofen Impurity 116 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.
