A method of determining adulteration of a fuel comprising subjecting to an analytical technique a marked fuel mixture comprising (a) a fuel; (b) a compound characterized by Formula I:
wherein X is carbon, oxygen, or sulfur; R1 and R2 each independently are hydrogen, C1 to C20 alkyl, or C6 to C10 aryl; R3 and R3' each independently are hydrogen or C1 to C4 alkyl; R4 and R4' each independently are hydrogen, C1 to C4 alkyl, C4 to C10 cycloalkyl, or C6 to C10 aryl; R5 and R5' each independently are C4 to C10 alkyl; R6 and R6' each independently are hydrogen or C1 to C6 alkyl; and R7 and R7' each independently are hydrogen or C1 to C4 alkyl; and (c) a heavy compound, wherein the heavy compound comprises a compound of Formula I having at least one atom replaced with an isotope tag.
A compound characterized by Formula I:
wherein X can be carbon (C), oxygen (O), or sulfur (S); R1 and R2 can each independently be hydrogen, a C1 to C20 alkyl group, or a C6 to C10 aryl group; R3 and R3' can each independently be hydrogen or a C1 to C4 alkyl group; R4 and R4' can each independently be hydrogen, a C1 to C4 alkyl group, a C4 to C10 cycloalkyl group, or a C6 to C10 aryl group; R5 and R5' can each independently be a C4 to C10 alkyl group; R6 and R6' can each independently be hydrogen or a C1 to C6 alkyl group; and R7 and R7' can each independently be hydrogen or a C1 to C4 alkyl group; and wherein the compound characterized by Formula I when subjected to gas chromatography-mass spectrometry (GC-MS) using electron ionization produces at least one ion having a mass-to-charge ratio of greater than about 300 at an ionization energy of equal to or greater than about 70 eV.
