Disclosed are oleyl propylenediamine-based compounds used in compositions and methods for inhibiting corrosion. The method comprises introducing into a fluid source a composition comprising one or more oleyl propylenediamine-based compounds comprising Formula I: wherein Y1, Y2, and Y3 independently are hydrogen or a substituent of Formula (II): wherein V is —O— or —NH—, W is optionally present and is a linear or branched C1-10 aliphatic group, X is —H, —NZ3+, —COOH, —SO3H, —OSO3H2, —PO3H, —OPO3H2, or a salt thereof, each Z independently is hydrogen or a linear or branched C1-20 aliphatic group optionally interrupted or substituted with one or more oxygen atoms, and R is hydrogen or methyl, provided that at least one of Y1, Y2, or Y3 is a substituent of Formula (II).
