General Description

Beta-naphthol violet, also known as 1-naphthol-4-sulfonic acid or Sudan IV, is a synthetic azo dye commonly used as a pH indicator and for various staining techniques in the laboratory. It is a toxic and potentially carcinogenic compound that is known for its strong affinity to bind to proteins, especially those found in the endoplasmic reticulum of cells. Beta-naphthol violet is also used as a coloring agent in the textile, food, and cosmetic industries. However, its use in consumer products is generally limited due to its potential health hazards and regulatory restrictions.
