FIELD: heterocyclic nitrogen-containing compounds.
SUBSTANCE: invention relates to derivatives of unsymmetrical triazines, which are the active basis of corrosion inhibitors for gas and oilfield equipment and oil transportation pipelines operating in highly mineralized hydrogen sulfide-containing environments. The essence of the invention consists in creating a corrosion inhibitor containing 4-amino-1,4,5,6-tetrahydro-1,2,4-triazinon-5 derivatives of the general formula as an active base: 
EFFECT: expanding the range of corrosion inhibitors.
