Description
Chromate(2-), 3-(hydroxy-.kappa.O)-4-2-(hydroxy-.kappa.O)-1-naphthalenylazo-.kappa.N2-1-naphthalenesulfonato(3-)1-2-(hydroxy-.kappa.O)-5-(4-methoxyphenyl)azophenylazo-.kappa.N2-2-naphthalenolato(2-)-.kappa.O-, disodium is a complex metallized azo dye with a specific chromium coordination structure. This compound is valued for its ability to impart durable, lightfast coloration in demanding industrial applications. It is primarily sought by manufacturers in the pigments, inks, and specialty coatings sectors who require high-performance colorants.
Application
- Manufacturing of high-performance industrial pigments for plastics and synthetic fibers.
- Formulation of specialty printing inks requiring excellent lightfastness and chemical resistance.
- Production of colored coatings and finishes for automotive and industrial components.
- As a colorant in the production of specialty papers and decorative laminates.
- Potential use in the dyeing of specific synthetic materials where metal-complex dyes are applicable.
- Research and development of novel colored materials in academic and industrial laboratories.

Quality Control
Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Quality parameters are strictly monitored to meet the specific requirements of pigment and ink applications. A Certificate of Analysis (COA) detailing purity, strength, and physical properties is available for every batch upon request.
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 sealed to prevent absorption of atmospheric moisture.
