Disclosed are selected biuret derivatives of 3-trihalomethyl-1,2,4-thiadiazole compounds of the formula: ##STR1## wherein R.sub.1 is a CCl.sub.3 or CF.sub.3 group; R.sub.2 and R.sub.3, separately, are either hydrogen or a lower alkyl group of 1 to 4 carbon atoms or an aryl group having 6 to 8 carbon atoms; and R.sub.4 and R.sub.5 are either hydrogen or a lower alkyl group of 1 to 4 carbon atoms or an aryl group having 6 to 8 carbon atoms or an acyl group having 1 to 8 carbon atoms, with the proviso that either R.sub.4 or R.sub.5, or both, must be a hydrogen.
披露了公式为:##STR1##的3-三卤甲基-1,2,4-噻二唑化合物的选择性联氨衍生物,其中R.sub.1是CCl.sub.3或CF.sub.3基团;R.sub.2和R.sub.3分别是氢或1至4个碳原子的较低烷基基团或具有6至8个碳原子的芳基团;R.sub.4和R.sub.5是氢或1至4个碳原子的较低烷基基团或具有6至8个碳原子的芳基团或具有1至8个碳原子的酰基团,但R.sub.4或R.sub.5,或两者都必须是氢。
