Compositions of heterocyclic compounds and uses as sulfidogenesis inhibitors

A method of sulfidogenesis inhibition in a hydrocarbon-containing system comprising a water injection system, a hydrocarbon extraction system, or a hydrocarbon production system, the method comprising administering an effective amount of a sulfidogenesis inhibitor compound of Formula 1 into the water injection system, the hydrocarbon extraction system, or the hydrocarbon production system, the compound of Formula 1 having a structure corresponding to:
