C.I. Acid Brown 97, with the CAS number 61901-18-6, is a synthetic dye primarily used in the textile industry for dyeing wool, silk, and nylon. It belongs to the class of acid dyes, which are characterized by their solubility in water and ability to form ionic bonds with positively charged sites on the fibers. This dye exhibits a brown color and is known for its good lightfastness and washfastness properties, making it suitable for various applications. The chemical structure typically includes sulfonic acid groups, which enhance its solubility in aqueous solutions. While it is effective for dyeing, safety considerations are important, as some azo dyes can release aromatic amines, which may pose health risks. Therefore, proper handling and adherence to safety guidelines are essential when working with this substance. Additionally, environmental regulations may apply to its use and disposal, necessitating awareness of local legislation regarding dye discharge and wastewater treatment.

<p>Acid brown 97 is a reaction product of peroxy-chloro-nitroso-cycloaliphatic compounds. It is used as an oxidizing agent in the production of chlorine and as a bleaching agent in the textile industry to remove stains from cotton, linen, and other fibres. When acid brown 97 comes into contact with wastewater, it reacts with the water to form hydrochloric acid and nitric acid. Acid Brown 97 has been shown to have an absorbance value at 420 nm of 0.2.</p>
