In the intricate world of scientific research and laboratory analysis, the reliability and purity of chemical reagents are paramount. Among these vital compounds, Solvent Red 43, commonly known as Eosin Y or Eosin Acid, stands out for its indispensable role in biological staining and precise chemical determination. As a leading manufacturer and supplier, understanding the applications and sourcing needs of B2B customers—from procurement managers to research scientists—is at the core of our mission. This article delves into why Solvent Red 43 is a cornerstone reagent and how partnering with a trusted supplier ensures quality and consistency for your critical applications.

Solvent Red 43 (CAS 15086-94-9) is an orange-red crystalline powder that possesses unique properties making it highly valuable in several scientific disciplines. Its primary application lies in histopathology, where it functions as a crucial biological stain. In this context, Eosin Y is used as a counterstain, typically following hematoxylin. It stains the cytoplasm, connective tissues, and other cellular components in varying shades of pink or red, providing excellent contrast with the blue-stained nuclei. This differential staining allows pathologists and researchers to clearly visualize cellular structures, making it easier to diagnose diseases and study tissue morphology. For laboratories demanding high-quality biological stains, sourcing Eosin Y from a reputable manufacturer in China guarantees the purity and consistency required for accurate diagnostic and research outcomes.

Beyond its role in microscopy, Solvent Red 43 is also recognized for its utility as an adsorption indicator in analytical chemistry. This means it can signal the endpoint of certain titrations by changing color when adsorbed onto a precipitate. Specifically, it is employed in the quantitative determination and titration of halide ions such as bromide and iodide. Its ability to provide a clear visual endpoint makes it a cost-effective and efficient tool for chemical analysis. Procurement managers looking to optimize laboratory processes can buy Solvent Red 43 for its dual functionality, streamlining analytical workflows and ensuring accurate results. When you purchase Solvent Red 43, understanding its analytical applications can reveal new efficiencies for your lab.
