Acid Red 92, commonly known as Phloxine B or Fluorescent Peach Red, is a water-soluble synthetic anionic fluorescent dye. It is chemically recognized as a halogenated fluorescein derivative (tetrabromotetrachlorofluorescein disodium salt) with the CAS number 18472-87-2.
Here are its primary uses and key selling points:
Main Uses
Biological & Medical Staining: Its most prominent application is in histology. It is highly effective at staining eosinophilic granules, such as those in Paneth cells of the small intestine, a vibrant red color. It is also used in specific staining protocols like Mallory's Phloxine-Methylene Blue and Kreyberg's methods for keratin and mucus.
pH & Fluorescent Indicator: Due to its pH sensitivity (especially in the 4.0–6.5 range) and strong fluorescence, it serves as a reliable indicator in analytical chemistry.
Textile Dyeing: As an acid dye, it has a strong affinity for protein-based fibers. It is used to dye wool, silk, and other substrates containing amino or hydroxyl groups.
Food Coloring (Regional): Known as "Food Red No. 104" in Japan, it is approved for use in confectioneries, cakes, beverages, and processed marine products within certain regions.
Cosmetics & Research: It acts as a colorant in various cosmetic formulations (subject to regional regulations) and serves as a high-contrast standard for calibrating colorimeters in material testing.
Key Selling Points
Vivid Fluorescent Color: It produces an exceptionally bright, saturated peach-red hue that remains highly visible even without an excitation light source, offering excellent visual contrast.
High Solubility & Clarity: The dye dissolves rapidly and cleanly in water, forming a clear solution with no precipitation or residue, which ensures uniform dyeing and easy handling.
Strong Affinity & Fast Uptake: It exhibits rapid coloring speed and strong binding power to protein fibers, making it highly efficient for textile applications and biological tissue staining.
Excellent Standardization: Because of its stable chemical properties and consistent color output, it is widely trusted as a reference standard for calibrating (color difference meters) in laboratory settings.
