C.I. Acid Brown 58, with the CAS number 12269-87-3, is a synthetic dye commonly used in various applications, particularly in the textile industry for dyeing wool, silk, and nylon. This azo dye is characterized by its brown color and is soluble in water, making it suitable for use in aqueous dyeing processes. The chemical structure typically features azo (-N=N-) linkages, which are common in many synthetic dyes, contributing to their color properties. Acid Brown 58 is classified as an acid dye, meaning it is applied in acidic conditions, which helps in achieving better fixation on protein fibers. While it is effective for its intended uses, it is important to note that some azo dyes have raised environmental and health concerns due to potential toxicity and the formation of carcinogenic amines upon degradation. Therefore, its use is regulated in many regions, and safety data sheets should be consulted for handling and disposal guidelines.

<p>Acid Brown 58 is a synthetic dye that is used for the quantification of skin surface tannins, or natural phenols. It reacts with aldehydes in the presence of iron and ammonia to produce a brown-black colour. Acid Brown 58 has been used to detect synthetic substances such as styryl, which are present in some variants of heroin. This dye also reacts with biological targets such as proteins and nucleic acids, and can be used as an indicator for substance abuse.</p>
