General Description

4-[(4,8-disulpho-2-naphthyl)azo]-3-hydroxy-2-naphthoic acid, also known as Acid Red 52, is a synthetic azo dye commonly used in textile and food industries. It is derived from naphthionic acid and contains a complex structure with naphthalene rings and azo groups. This chemical is a dark red powder and is soluble in water. It is used as a dye for fabrics, leather, and paper. Additionally, it is also used as a food coloring agent, particularly in the coloring of beverages and confectionery products. In some studies, its potential carcinogenic and mutagenic properties have been observed, leading to restrictions on its use in certain countries.
