Description

Disodium 3-Methyl-5-[(6-Sulphonato-2-Naphthyl)Azo]Salicylate is a synthetic, water-soluble azo dye salt characterized by its vivid color and good lightfastness. This compound matters for its role as a key intermediate and colorant in demanding industrial applications where consistent shade and chemical stability are paramount. It is primarily needed by manufacturers in the textile, leather, and specialty ink industries for dyeing and printing processes. Its structure also lends itself to potential use in the formulation of analytical reagents and colorimetric indicators.

Application

• Textile Dyeing: Used for coloring natural and synthetic fibers, particularly where bright, wash-fast shades are required.
• Leather Finishing: Applied in the dyeing of leather goods to achieve uniform and durable coloration.
• Ink Formulation: Serves as a pigment or dye component in the production of specialty printing inks.
• Paper Coloring: Employed in the tinting of specialty papers and paper products.
• Biological Staining: Potential use as a histological or cytological stain in laboratory settings.
• Chemical Intermediate: Acts as a precursor in the synthesis of more complex dyes and organic compounds.

Quality Control

Our Disodium 3-Methyl-5-[(6-Sulphonato-2-Naphthyl)Azo]Salicylate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for color strength, purity, and chemical composition. Certificates of Analysis (COA) detailing key parameters such as assay, hue, and impurity profiles are available upon request to support your quality assurance protocols.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance and handling.
