Description

7-[[[[4-(Acetylamino)Phenyl]Amino]Carbonyl]Amino]-4-Hydroxy-3-[(2-Methoxyphenyl)Azo]-2-Naphthalenesulfonic Acid Sodium Salt is a high-purity, water-soluble azo dye intermediate of significant commercial importance. Its value lies in its role as a key precursor for synthesizing specialized dyes and pigments, particularly those requiring specific color fastness and stability properties. This compound is essential for manufacturers in the textile, ink, and specialty chemical industries seeking to develop advanced colorants.

Application

• Primary intermediate for the synthesis of azo dyes and pigments used in textile coloration.
• Key precursor in the production of specialty inks, including those for packaging and security printing applications.
• Used in the manufacturing of colorants for plastics and polymers to achieve specific hues and performance characteristics.
• Research and development of novel functional dyes for non-textile applications, such as in optical data storage or sensors.
• Potential use as a biological stain or histochemical reagent in laboratory settings, given its chromophoric structure.
