    Abstract: A method for marking a petroleum hydrocarbon or a liquid biologically derived fuel. The method comprises adding to a petroleum hydrocarbon or a liquid biologically derived fuel at least one compound having formula (I), wherein R is C1-C12 alkyl, C3-C12 alkenyl or C7-C12 aralkyl; wherein each compound having formula (I) is present at a level from 0.01 ppm to 50 ppm.

    Abstract: Marking a petroleum product includes adding a covert dye selected from the group consisting of azadipyrromethene dyes, dipyrromethene dyes, and any combination thereof to the petroleum product and distributing the dye in the petroleum product. A petroleum product selected for analysis may be spectroscopically analyzed for the presence of an azadipyrromethene dye, a dipyrromethene dye, or a combination thereof. A concentration of at least one azadipyrromethene or dipyrromethene dye present in the portion of the petroleum product may be determined to identify the petroleum product as counterfeit, adulterated, or authentic based on the determined concentration of the azadipyrromethene or dipyrromethene dye.
