3-[2-[4-(Diethylamino)-2-hydroxyphenyl]diazenyl]-4-hydroxybenzenesulfonic acid

Description:
3-[2-[4-(Diethylamino)-2-hydroxyphenyl]diazenyl]-4-hydroxybenzenesulfonic acid, commonly known as a diazo dye, is characterized by its vibrant color and is primarily used in dyeing applications, particularly in textiles. This compound features a sulfonic acid group, which enhances its solubility in water, making it suitable for various aqueous dyeing processes. The presence of the diethylamino group contributes to its stability and reactivity, allowing it to form strong bonds with fabric fibers. Additionally, the hydroxyl groups in its structure can participate in hydrogen bonding, further influencing its dyeing properties. The compound is typically synthesized through azo coupling reactions, which involve the reaction of diazonium salts with phenolic compounds. As with many azo dyes, it is important to consider its environmental impact and potential toxicity, as some azo compounds can release harmful amines upon degradation. Overall, this substance is notable for its application in the dye industry, particularly for producing bright and lasting colors on various materials.
