Quantitative determination of some pharmaceuticals in bulk drugs and tablets by proton magnetic resonance (PMR) spectroscopy.
The quantitation of allopurinol, I, flucytosine, II, meclophenoxate hydrochloride, III, and phenylephrine hydrochloride, IV, in bulk drugs and tablets was achieved by simply developed, rapid and specific methods using the proton magnetic resonance (PMR) spectroscopy. Trifluoroacetic acid and dimethylmalonic acid were the solvent and the internal standard respectively.
