General description

This substance belongs to the class of azo dyes. Find here a comprehensive listingof all our food colorant reference materials.

Disperse Orange 3 is widely used in textile industry for dyeing polyester fibers.

Application

Disperse Orange 3 may be used as a test material for investigating its degradation by the white rot fungus Pleurotus ostreatus and the products obtained upon degradation are determined using UV-visible spectrophotometric and high-performance liquid chromatographic techniques.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Features and Benefits

Used to provide experimental verification of a two-level model for the enhancement of the nonresonant, nonlinear refractive index, with a decrease in absorption by reduction of a donor group strength.
