Solvent Red 23 (CAS 85-86-9) is a highly versatile solvent dye that plays a crucial role across numerous industrial sectors, extending its utility far beyond its well-known applications in plastics. Renowned for its brilliant red hue and excellent solubility in nonpolar substances, this azo dye is a key component in formulations ranging from printing inks to specialized industrial lubricants.

Beyond Plastics: A Spectrum of Applications

While its use in coloring polymers like ABS, PVC, and PMMA is extensive, Solvent Red 23's inherent solvency properties make it ideal for other demanding applications. Its ability to dissolve readily in oils, greases, waxes, and hydrocarbon solvents allows it to impart a distinct red color to:

  • Printing Inks: Solvent Red 23 is frequently used in the formulation of ballpoint pen inks, providing a bright, consistent red color that flows smoothly. Its solvency ensures it remains dissolved and doesn't clog pen tips.
  • Greases and Lubricants: In the automotive and industrial machinery sectors, it's used to color greases and lubricating oils. This coloration serves not only for product identification but also to indicate specific grades or types of lubricant.
  • Waxes and Petroleum Products: The dye is applied to color various waxes and petroleum-based products, including fuels and oils, aiding in differentiation and tracking.
  • Fibers: It can be used for coloring synthetic fibers, such as in the raw pulp stage of materials like terylene, contributing to the final textile's visual appeal.
  • Biological Staining: In laboratory settings, Solvent Red 23 is recognized for its use as a biological stain, particularly effective in demonstrating triglycerides in frozen tissue sections, making it valuable in histopathology and research.

Sourcing High-Quality Solvent Red 23

For businesses requiring Solvent Red 23 for these diverse applications, securing a reliable supply is crucial. Leading chemical manufacturers and suppliers, particularly those operating from China, offer this dye with high purity (often exceeding 97% by HPLC) and consistent performance characteristics. When you plan to buy Solvent Red 23, it is advisable to work with suppliers who can provide comprehensive technical data sheets, certificates of analysis, and samples for quality verification. Prioritizing suppliers with strong experience in industrial dyes ensures you receive a product that meets stringent application requirements and offers competitive pricing for bulk orders.

In conclusion, the wide-ranging utility of Solvent Red 23 underscores its importance as a fundamental industrial chemical. Its bright red color and excellent solvency properties make it a valuable asset for manufacturers across multiple sectors. We encourage procurement professionals and formulators to connect with established suppliers to explore how Solvent Red 23 can enhance their products.
