Description

2-[[8-[[(2,3-Dichloroquinoxalin-6-Yl)Carbonyl]Amino]-1-Hydroxy-3,6-Disulpho-2-Naphthyl]Azo]Naphthalene-1,5-Disulphonic Acid, Lithium Sodium Salt is a high-purity, water-soluble organic dye intermediate with a complex polycyclic structure. This compound matters for its role as a critical precursor in synthesizing high-performance, azo-based dyes and pigments, particularly those requiring specific shades, lightfastness, and solubility profiles. Industries that need this specialized chemical include manufacturers of textile dyes, inkjet inks, and specialty colorants for technical applications.

Application

• Primary Intermediate for Azo Dyes: A key building block in the synthesis of high-value, complex azo dyes for textiles, leather, and paper.
• Specialty Pigment Manufacturing: Used in the production of pigments requiring enhanced solubility, brightness, and specific chromatic properties.
• Inkjet Ink Formulations: Serves as a precursor for dyes used in high-quality digital printing inks, where color purity and stability are paramount.
• Functional Dye Synthesis: Potential use in creating dyes for non-textile applications, such as sensitizers for dye-sensitized solar cells (DSSCs) or analytical reagents.
• Research & Development: Employed in chemical R&D for developing novel chromophores and studying structure-property relationships in dye chemistry.

Quality Control

Our production of this dye intermediate adheres to strict quality protocols to ensure batch-to-batch consistency and purity for sensitive synthesis processes. Quality is verified through advanced analytical techniques including HPLC, UV-Vis spectroscopy, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and R&D needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect purity and handling properties.
