Description

Chromate(3-), [3-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo]-2-hydroxy-5-nitrobenzenesulfonato(3-)][3-hydroxy-4-[(2-hydroxy-1-naphthalenyl)azo]-7-nitro-1-naphthalenesulfonato(3-)]-, sodium is a complex, high-purity azo dye metal salt primarily used as a specialized colorant and functional additive. This compound matters for its ability to provide intense, stable coloration and specific chemical interactions in advanced material formulations. It is essential for industrial and research applications requiring precise chromophoric properties, such as in the manufacturing of specialized pigments, analytical reagents, and functional coatings.

Application

• Specialized Pigment Manufacturing: Used as a key intermediate or colorant component for producing high-performance organic pigments.
• Analytical Chemistry & Reagents: Serves as a complexometric indicator or a chromogenic agent in specific titration and colorimetric analysis methods.
• Functional Dyes for Polymers: Imparts color and potentially other functional properties to engineering plastics, synthetic fibers, and specialty films.
• Research & Development: Employed in chemical synthesis and material science research for developing new dyes, sensors, or photoactive materials.
• Inks and Coatings: Formulated into specialty inks for printing or functional coatings where specific light absorption properties are required.
• Historical Textile Dyeing (Niche): May find use in the reproduction of historical textile colors or in art conservation science.

Quality Control

Our Chromate(3-), [3-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo]-2-hydroxy-5-nitrobenzenesulfonato(3-)][3-hydroxy-4-[(2-hydroxy-1-naphthalenyl)azo]-7-nitro-1-naphthalenesulfonato(3-)]-, sodium is produced under a rigorous quality management system. Each batch undergoes comprehensive testing to ensure consistency in color strength, purity, and chemical composition. Certificates of Analysis (COA) detailing key specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 each use to prevent absorption of atmospheric moisture, which can affect product performance.
