Rhodamine B (Cat No.: R024429) is a bright pink, water-soluble xanthene dye widely used as a fluorescent tracer, staining agent, and pH indicator in biological, chemical, and environmental applications. It exhibits strong absorption and emission in the visible spectrum, making it ideal for fluorescence microscopy, flow cytometry, and spectroscopy. Rhodamine B readily binds to cellular components, allowing for vivid visualization in staining protocols. It is also employed in dye lasers and leak detection systems due to its high quantum yield and photostability.
