4-(Acetylamino)-5-hydroxy-2,7-naphthalenedisulfonic acid

Description:

4-(Acetylamino)-5-hydroxy-2,7-naphthalenedisulfonic acid, commonly referred to as "Naphthol AS-OL," is an organic compound characterized by its naphthalene structure substituted with both acetylamino and hydroxy groups, as well as two sulfonic acid groups. This compound is typically a dark-colored solid that is soluble in water, making it useful in various applications, particularly in dye chemistry and as a reagent in analytical chemistry. Its sulfonic acid groups contribute to its acidity and enhance its solubility in aqueous solutions. The presence of the hydroxy group allows for potential hydrogen bonding, which can influence its reactivity and interactions with other molecules. Naphthol AS-OL is often utilized in the synthesis of azo dyes and as a pH indicator due to its ability to change color in response to pH variations. Additionally, it has applications in biological staining and as a chemical intermediate in organic synthesis. Safety precautions should be observed when handling this compound, as it may pose health risks upon exposure.
