The scope of the notification is 4-(3-fluorophenyl)-1-(4-methylimidazol-5-yl)thio-semicarbazide, as outlined in the drawing. The notification shall also include the following: the relationship and mode of its production, which is that 4-methyl-5-imidazole-5-carboxylic acid hydrazide undergoes an isothiocyanate reaction with a molar ratio 1:1, the reaction is carried out in an anhydrous ethanol environment at the boiling point of the solvent favourably when the reaction time is 30-min.,the product obtained is then cooled,the precipitated sediment is drained,and crystallizes after drying.
