Chemical Structure

Mepyramine EP Impurity C CAS 24843-39-8 chemical structure

Description

The occurrence of Mepyramine EP Impurity C is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Mepyramine EP Impurity C (CAS 24843-39-8) is a certified pharmaceutical impurity reference standard with the molecular formula C5H6N2 and a molecular weight of 94.11 g/mol.

Mepyramine EP Impurity C (C5H6N2) contains a nitrile group. Its physicochemical properties are representative of its class; 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
