Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 79932-20-0, C6H10N2S.

Products of the nitration of 2-thiazolylurea and 2-thiazolylthiourea derivatives with fuming nitric acid in concentrated sulfuric acid are described. The urea derivatives studied were 3-(4-methyl-2-thiazolyl)urea and -thiourea (7), and their 1-methyl (1 and 2, respectively) and 1,1-dimethyl analogs. The products were the compounds nitrated at the 5-position of the thiazole moiety. With an excess of nitric acid, 1-methyl-3-(4-methyl-5-nitro-2-thiazolyl)-1-nitrourea was obtained from 1, while the corresponding 1-nitrosourea was found from 2. A pale yellow compound was obtained from the nitration of 7. Unlike other nitrated thioureas, it did not form a colored Cu(II) chelate and was stable to acid, alkali, and heat. It was concluded to be 6-methyl-2-nitroiminothiazolo[3,2-b][1,2,4]thiadiazole from studies of its physiochemical properties, chemical reactions, and the results of X-ray crystallography. Corresponding compounds were obtained from other N-(4-alkyl-2-thiazolyl)thioureas.
