    Abstract: Novel disazo colorants or dyes for marking organic liquids, the colorants having the general formula

    WHERE R1 is H, CF3, or alkyl having from 1 to 4 carbon atoms, R2 is H, or alkyl having from 1 to 4 carbon atoms, R3 and R4 are each H, OCH3, OC2H5 or CH3, and R5, R6 and R7 are each H, or alkyl having from 1 to 12 carbon atoms, at least one of said R5, R6 and R7 being alkyl. The novel compound of the general formula

    WHERE R5, R6 and R7 are as described above is provided and is useful as an intermediate in the preparation of said disazo colorants. Methods for the preparation of the colorants are disclosed together with qualitative and quantitative procedures for detecting these colorants in the marked liquids.
