Chemical Structure

Ketoprofen Impurity 113 CAS CATO-C4X-1471113 chemical structure

Description

The occurrence of Ketoprofen Impurity 113 is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ketoprofen Impurity 113 (CAS CATO-C4X-1471113) is a certified pharmaceutical impurity reference standard with the molecular formula C19H18O4 and a molecular weight of 310.34 g/mol.

Based on its molecular formula C19H18O4, Ketoprofen Impurity 113 contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 310.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Ketoprofen Impurity 113 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.
