FIELD: chemistry.
SUBSTANCE: disclosed is a 3-butyl-5-oxy-5-perfluorooctyl-4,5-dihydro-1H-pyrazole-1-carbothioamide of formula given below (1) as material for a standard sample of a composition for quantitative determination of fluorine (mass fraction from 50 to 70 %) and sulphur (mass fraction from 5 to 13 %) in organic compounds of various nature. In addition, disclosed is a method for production thereof, involving reaction of lithium (1,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-heptadecafluoropentadecadionate-9,11) with thiosemicarbazide hydrochloride in molar ratio 1:1 while boiling in ethanol.
EFFECT: disclosed is a 3-butyl-5-oxy-5-perfluorooctyl-4,5-dihydro-1H-pyrazole-1-carbothioamide as a standard sample of a composition for quantitative determination of fluorine and sulphur in organic compounds and a method for production thereof.
