6341-28-2 Usage
General Description
Disodium 7-[(4-amino-5-methoxy-o-tolyl)azo]naphthalene-1,3-disulphonate, commonly known as Disodium Orange G, is a synthetic, water-soluble azo dye that is commonly used as a food coloring and in the textile industry. It is a bright orange powder that is sparingly soluble in water and insoluble in organic solvents. It is often used to color foods, beverages, and medications, and is known for its high stability, strong color, and resistance to fading. Because of its color intensity and stability, Disodium Orange G is also used in the textile industry to dye cotton, wool, and silk fabrics. However, concerns have been raised about its potential health effects due to its azo chemical structure, and some countries have restricted its use in food products.
