Dyes & pigment intermediates, also known as intermediates, generally refer to various aromatic hydrocarbon derivatives used in the production of dyes and organic pigments. The most important dye intermediates are o-nitrochlorobenzene, p-nitrochlorobenzene, o-nitrotoluene, p-nitrotoluene, 2-naphthol, anthraquinone, 1-aminoanthraquinone, etc.
