The synthetic azo dye Disperse Orange 31 was wrongly substituted by Disperse Orange 3 in patch test materials from Chemotechnique. This situation explains why a relatively low percentage of patients positive to PPD were positive to Disperse Orange 3, although a coreaction is explained to be very frequent because of skin transformation of Disperse Orange 3 into PPD.
3-[[2-(acetyloxy)ethyl][4-[(4-nitrophenyl)azo]phenyl]amino]propiononitrile Use and Manufacturing
Taking p-nitroaniline and N-cyanoethyl-N-acetoxyethyl aniline as raw materials, first diazotize the former and then couple with the latter to obtain the product. After filtering, grinding and drying, the finished product is obtained.
Used for dyeing polyester and its blended fabrics
Disperse orange 31 is an orange-orange dye commonly used for fiber dyeing.
