C.I. Acid Brown 289, with the CAS number 12219-72-6, 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 their ability to form ionic bonds with positively charged sites on protein fibers. This dye exhibits a brown color and is known for its good lightfastness and washfastness properties, making it suitable for applications where durability is essential. The chemical structure of Acid Brown 289 typically includes azo groups, which are responsible for its color properties. As with many synthetic dyes, it is important to handle this substance with care, as it may pose environmental and health risks if not managed properly. Safety data sheets should be consulted for information on handling, storage, and disposal to ensure compliance with safety regulations.
