Understanding the scientific underpinnings of this dye—its chemical properties, applications, and emerging uses—is essential for B2B users, researchers, and formulators. As a leading manufacturer and supplier, we are committed to providing high-quality Acid Blue 113 and sharing insights into its scientific importance.

Chemical Profile of Acid Blue 113

Acid Blue 113 is characterized as a water-soluble, anionic dye belonging to the disazo chemical family. Its molecular formula, C32H24N5NaO6S2, and molecular weight of approximately 661.68 g/mol, indicate a complex organic structure. The anionic nature of the dye means it carries a negative charge, which facilitates its binding to positively charged sites on substrates, particularly protein and polyamide fibers found in wool, silk, and nylon. This ionic interaction is fundamental to its effectiveness in textile dyeing.

The dye's physical appearance is typically described as a greenish-black powder, with a purity often exceeding 99.0%. Its solubility in water allows for easy application in aqueous dyeing baths. The spectral properties, such as its lambda max (λmax) around 560nm, are critical for color matching and quality control in industrial processes. These scientific parameters define its behavior and performance in various applications.

Diverse Industrial Applications

The primary applications of Acid Blue 113 leverage its strong affinity for specific materials:

• Textile Industry: It is a staple for dyeing wool, silk, and nylon fibers, providing vibrant, deep blue shades with good fastness properties. Its ability to dye these materials evenly makes it indispensable for apparel and furnishing manufacturers.
• Leather Industry: Acid Blue 113 is used to color leather, offering rich blue tones that enhance the aesthetic appeal of finished leather goods.
• Paper Industry: It serves as a colorant for various paper products, ensuring consistent and bright blue coloration.
• Biological Staining: In scientific research and laboratories, it is employed for staining biological samples, aiding in microscopy and analysis.

Emerging Role in Environmental Science
