Orange G dye

There is a large number of heteroaromatic coupling components of very different structural types. l-Aryl-3-methyl-5-pyrazolones have been widely used for yellow and orange monoazo dyes since the end of the 19th century. Other types have become important as a source of new industrially produced dyes in the last two decades. In reviews on industrial aspects (e.g., Schwander, 1982) these coupling components are classified not on the basis of their structures, but from the viewpoint of what is important for tinctorial properties of the dyes obtained with these types of coupling components. Here we will use a structural approach to systematization.

FUR of the materials used in consumer products can be applied, after a reduction process with Na2S2C>4, for forensic detection of forbidden azo dyes. Thus, the spectra of yarns which were dyed with Direct Brown 95 (116) and Direct Orange G (117) showed, respectively, after reduction the strongest peaks of benzidine (7b) and 3,3 -dimethylbenzidine (7d) protruding over the matrix background196.
