DescriptionDisperse orange 3 is an azo dye which can induce contact dermatitis in workers in the textile industry. Patch tests are frequently positive (about 30%) in hairdressers with a hand dermatitis. It is probably an indicator of contact sensitization to PPD, but disperse orange 3 can also be found in so me semipermanent hair dyes.

UsesDisperse orange 3 is used as a dye in acetate, nylon, silk, wool, and cotton; stocking dye.

UsesDisperse Orange 3 may be used as a test material for investigating its degradation by the white rot fungusPleurotus ostreatus and the products obtained upon degradation are determined using UV-visible spectrophotometric and high-performance liquid chromatographic techniques.

General DescriptionDisperse Orange 3 (DO3) is a monoazo dye, which contains 90% dye content plus dispersing agents and surfactants. It has two aromatic rings with an amino group on one of the rings and the other is substituted with a nitro group. It shows an absorption peak majoring at 415 nm.

Preparation methods

Preparation4-Nitrobenzenamine diazo, with aniline base armour sulfonic acid coupling, and sodium hydroxide solution to boil, then a sulfonic acid hydrolysis off base.
