Mycophenolate Mofetil Impurity 17 CAS 26644-06-4 chemical structure

Description

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.

Mycophenolate Mofetil Impurity 17 (CAS 26644-06-4) is a certified pharmaceutical impurity reference standard with the molecular formula C17H20O7 and a molecular weight of 336.34 g/mol.

Mycophenolate Mofetil Impurity 17 (C17H20O7) contains a flavonoid core, a hydroxyl group, an ether linkage. 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).

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.
