No. of bitstreams: 0 Previous issue date: 2010-01-01 A qualitative spot-test and tandem quantitative analysis of dipyrone in the bulk drug and in pharmaceutical preparations is proposed. The formation of a reddish-violet color indicates a positive result. In sequence a quantitative procedure can be performed in the same flask. The quantitative results obtained were statistically compared with those obtained with the method indicated by the Brazilian Pharmacopoeia, using the Student fst and the F tests. Considering the concentration in a 100 μL aliquot, the qualitative visual limit of detection is about (Formula Presented) instrumental (Formula Presented) State University of Campinas - UNICAMP Institute of Chemistry, P.O.
