Description

Benzenesulfonic Acid, 4-Amino-, Diazotized, Coupled With Dyer'S Mulberry Extract, Sodium Salts is a specialized synthetic dye belonging to the azo dye class, derived from a diazotized aromatic amine coupled with a natural extract. This compound is valued for its ability to impart consistent and vibrant coloration, particularly in shades of brown, red, and violet, with good affinity to various substrates. It is primarily required by manufacturers in the textile, leather, and specialty ink industries seeking reliable and specific colorants for their dyeing and printing processes.

Application

• Textile Dyeing: Primary application for dyeing natural and synthetic fibers, including cotton, wool, and nylon, to achieve specific brown and red hues.
• Leather Finishing: Used in the dyeing of leather goods such as footwear, bags, and upholstery to provide rich, uniform color.
• Ink Formulation: A key colorant component in the production of specialty inks for packaging, security printing, and artistic applications.
• Paper Coloration: Employed in the tinting of specialty papers, including decorative and security papers.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis, depending on purity.
• Wood Staining: Can be utilized in formulations for staining wood to enhance its aesthetic appeal.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is analyzed for key parameters including color strength, shade, solubility, and impurity profile to guarantee batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing specific test results are available upon request. We adhere to ISO 9001 quality management principles, and our processes can support compliance with relevant regulations for target markets, including REACH.

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 to prevent absorption of atmospheric moisture, which can affect product performance and stability.
