2,5-Dichloroaniline is an organic compound with the formula C6H3Cl2NH2. One of six isomers of dichloroaniline, it is a colorless solid that is insoluble in water. It is produced by hydrogenation of 1,4-dichloronitrobenzene. It is a precursor to dyes and pigments, e.g., Pigment Yellow 10. Pigment Yellow 10, a derivative of 1,4-dichloroanilne, is commonly used for yellow road markings in the US.
