Disperse Orange 73(CAS: 79300-11-1)

Disperse Orange 73 (CAS: 79300-11-1) is a water-insoluble azo dye with a crystalline form. It has a molecular weight of approximately 562.4 g/mol and exhibits good light and heat stability. The dye is moderately soluble in organic solvents like acetone and alcohols but is practically insoluble in water. Its chemical reactivity is minimal due to its azo linkage, making it stable under normal conditions.

Disperse Orange 73 (CAS: 79300-11-1) is synthesized through a typical azo coupling reaction using a nitrobenzene derivative and an aromatic amine. Common catalysts include acids or Lewis acids, and the reaction proceeds under acidic conditions. The yield is typically high, and the product is purified by recrystallization or precipitation.

Disperse Orange 73 (CAS: 79300-11-1) is widely used in the textile and dyeing industries for coloring synthetic fibers. It is also applied in the paper and printing industries for coloring paper and ink. Additionally, it can be used in the plastics industry for coloring plastic products and in the leather industry for dyeing leather goods.

When handling Disperse Orange 73 (CAS: 79300-11-1), it is essential to use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Store the dye in a dry, well-ventilated area and avoid contact with water and oxidizing agents. In case of a spill, clean up using appropriate methods as outlined in the Material Safety Data Sheet (MSDS/SDS). Ensure proper handling and disposal to prevent environmental contamination.
