Thiosemicarbazide as a reagent for the identification of aldehydes, ketones, and quinones

Abstract

Abstract For chemotherapeutic studies and for evaluation of thiosemicarbazones as characteristic derivatives for the identification of carbonyl compounds, a large number of thiosemicarbazones have been prepared. The virtue of thiosemicarbazide as a reagent in qualitative organic analysis has been discussed. Most of the thiosemicarbazones prepared show very high in vitro antitubercular activity. A few of them have been shown to possess activity even higher than that of streptomycin.
