General Description

4-amino-3-[4-(2-sulfooxyethylsulfonyl)phenyl]azo-naphthalene-1-sulfonic acid, also known as Acid Orange 7, is a synthetic azo dye commonly used in the textile industry. It is classified as a sulfonic acid and contains a naphthalene backbone with an azo group and a sulfonic acid group. The compound is water-soluble and has a bright orange color, making it suitable for use as a dye in various applications. However, it has been found to be a potential health hazard and environmental pollutant, as it can cause skin and eye irritation and is resistant to biodegradation. Consequently, there are efforts to regulate and minimize the use of this chemical in industrial processes.
