Definition

ChEBI: Disperse Blue 124 is a monoazo compound consisting of diazene with a 5-nitrothiazol-2-yl group attached to one nitrogen and a substituted 4-aminophenyl group attached to the other; used as a dye standard for the assay of allergy-releasing dyes in textiles. It has a role as a dye, a hapten and an allergen. It is a member of 1,3-thiazoles, a monoazo compound and a tertiary amine.

Contact allergens

This clothing dye used in synthetic fibers is one of the most potent sensitizers in clothes. It is a textile dye responsible for occupational contact dermatitis in the textile industry. A positive patch test reaction was observed in a painter sensitized to phthalocyanine dyes, with no occupational relevance. Constant concomitant reactions with Disperse Blue 106, and even to photographic developers CD1-4, are due to their chemical similarities.
