Description

Sodium 6-Amino-4-Hydroxy-5-[[2-(Trifluoromethyl)Phenyl]Azo]Naphthalene-2-Sulphonate is a specialized azo dye intermediate and a high-value chromophore, prized for its ability to impart vivid and stable color properties. Its core value lies in its unique molecular structure, which combines a naphthalene sulphonate backbone with a trifluoromethyl-substituted phenylazo group, offering enhanced lightfastness and chemical resistance. This compound is essential for manufacturers in the dyes and pigments, specialty inks, and advanced material coating sectors seeking to develop high-performance colorants.

Application

• Primary Intermediate for High-Performance Dyes: A key building block in the synthesis of acid dyes, direct dyes, and reactive dyes, particularly for textiles like nylon, silk, and wool that require excellent wash and light fastness.
• Specialty Ink Formulations: Used in the production of inks for jet printing, security printing, and other applications where color intensity and stability are critical.
• Functional Pigments for Coatings: Incorporated into industrial and automotive coatings to provide durable, fade-resistant coloration.
• Laboratory Reagent and Research Chemical: Serves as a standard or intermediate in organic synthesis and chromatographic analysis for research and development.
• Potential Use in Optical Materials: Its specific chromophoric system makes it a candidate for research in non-linear optics and photonic devices.
