Description

Chromate(5-), Bis2-6-4-Chloro-6-4-(4-Sulfophenyl)Azophenylamino-1,3,5-Triazin-2-Ylamino-1-Hydroxy-3-Sulfo-2-Naphthalenylazobenzoato(4-)-, Pentasodium is a complex, high-performance chromium-based azo dye intermediate. This compound matters for its role in synthesizing specialized, high-value dyes and pigments with enhanced color fastness and stability properties. It is primarily needed by manufacturers in the textile, leather, and specialty chemical industries seeking to produce advanced coloring agents.

Application

• Textile Dyeing: As a key intermediate for producing high-grade, wash-fast azo dyes for natural and synthetic fibers.
• Leather Finishing: Used in the synthesis of pigments and dyes for coloring leather goods with improved light and rub fastness.
• Specialty Pigment Manufacturing: Serves as a precursor for creating complex inorganic-organic hybrid pigments used in coatings and plastics.
• Research & Development: A valuable chemical building block in R&D labs for developing novel chromogenic materials and sensors.
• Paper Coloring: Employed in the production of dyes for high-quality paper and packaging materials requiring specific color properties.
• Ink Formulation: Acts as an intermediate for manufacturing specialized printing inks, particularly where color intensity and stability are critical.

Quality Control

Our production of this dye intermediate adheres to strict quality control protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through analytical methods including HPLC and spectrophotometry to confirm identity and purity. A Certificate of Analysis (COA) detailing specific lot parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 absorption of atmospheric moisture.
