Application of PMR spectrometry in pharmaceutical analysis.
Noramidopyrine-methansulfonate sodium (dipyrone), in bulk drug and its Novalgin ampules, has been assayed by a new, rapid, accurate and specific method. It involves the use of PMR Spectrometry; in which the integral of the five aromatic protons present in dipyrone is compared to that of the two protons of a known amount of maleic acid used as internal standard.
