Mefenamic Acid EP Impurity E CAS 4869-11-8

Description

Compared with other compounds in its class, the molecular weight of 197.28 g/mol gives Mefenamic Acid EP Impurity E distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Mefenamic Acid EP Impurity E (CAS 4869-11-8) is a certified pharmaceutical impurity reference standard with the molecular formula C14H15N and a molecular weight of 197.28 g/mol.

Mefenamic Acid EP Impurity E (C14H15N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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), Mefenamic Acid EP Impurity E 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.
