Description

Trisodium 7-[[4-[[[[2-Methoxy-4-[(3-Sulphonatophenyl)Azo]Phenyl]Amino]Carbonyl]Amino]-o-Tolyl]Azo]Naphthalene-1,3-Disulphonate is a high-purity, water-soluble azo dye intermediate known for its excellent chromophore properties and stability. This compound is critical for synthesizing vibrant and durable dyes and pigments, offering superior color strength and fastness. It is primarily required by manufacturers in the textile, ink, and specialty coatings industries for producing high-performance colorants.

Application

• Primary intermediate for the synthesis of reactive and direct dyes used in textile dyeing and printing.
• Key component in manufacturing pigments for inks, including those for packaging and commercial printing.
• Used in the production of colorants for specialty coatings and paints requiring high lightfastness.
• Intermediate for paper coloring agents, providing consistent and bright hues.
• Potential use in the synthesis of functional dyes for non-textile applications, such as in electronics or sensors.
• Research and development of novel chromogenic materials in academic and industrial laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and potential degradation.
