The present invention relates to a composition, a method for preparing a composition, and a method for analyzing the composition where the composition includes a liquid hydrocarbon and one or more marker compounds of formula (I) where Y is selected from X-R2 or NR3R4, and where X is an oxygen atom or a sulfur atom, R2 is an organic radical having from about 1 to about 30 carbon atoms, R3 and R4 are the same or different organic radical having from about 1 to about 30 carbon atoms The markers can be present in the amounts from about 05 parts per million to about 50 parts per million, preferably from about 05 to about 25 parts per million and preferably from about 1 to about 10 parts per million and is usable to identify not only the source and identity of the particular hydrocarbon liquid, but also to allow expedient tracing of the hydrocarbon back to its source and analysis of the particular type of additives that may be present and to what extent they are present in the hydrocarbon.
