Description
Folic Acid Impurity 10 (CAS 8064-47-9) is a certified pharmaceutical impurity reference standard with the molecular formula C19H19N7O6C6H9NO3S and a molecular weight of 616.61 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Folic Acid Impurity 10 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 616.61 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.
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.
