Description

Cationic Blue m-Rl CAS NO 53124-74-6 is a synthetic cationic dye belonging to the triarylmethane class, valued for its intense blue coloration and affinity for polyanionic substrates. Its primary commercial significance lies in its effectiveness as a staining agent for biological tissues and industrial materials, providing high contrast and color fastness. This product is essential for manufacturers and laboratories in the histology, textile, paper, and specialty ink industries requiring reliable and consistent blue dyes.

Application

• Histological Staining: Used as a key component in staining kits for microscopic visualization of cellular and tissue structures in pathology and research.
• Textile Dyeing: Imparts a vibrant blue shade to acrylic fibers, modified nylons, and other synthetic materials that carry a negative charge.
• Paper Coloring: Employed in the production of specialty colored papers, including security papers and decorative stocks.
• Ink Manufacturing: Serves as a colorant for inks used in flexographic, inkjet, and other printing applications, particularly on cationic pre-treated substrates.
• Biological Indicators: Utilized in diagnostic assays and test strips as a colorimetric indicator due to its pH-dependent color changes.
• Leather Finishing: Applied in the dyeing of leather goods to achieve uniform and deep blue finishes.

Quality Control

Every batch of Cationic Blue m-Rl is manufactured and tested under a strict quality management system. Our products undergo rigorous quality testing to ensure compliance with industry standards for identity, purity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, absorbance, and impurity profile are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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 stability.
