ABOUT PRODUCT

What is Phenosafranine?

Phenosafranine is a synthetic cationic dye belonging to the phenazinium chloride family of basic dyes. It appears as a dark green crystalline powder that dissolves in water and ethanol to form a brilliant red solution. Phenosafranine is well-known not only for its biological staining properties but also for its remarkable role as a photosensitizer, redox indicator, DNA intercalator, and micelle probe in advanced scientific research.

INDUSTRIAL APPLICATIONS

Applications of Phenosafranine

Phenosafranine is widely used as a histological dye to stain cell nuclei, lignified tissues, and connective structures with sharp contrast for clear microscopic visualization.

Phenosafranine is one of the most studied photosensitizers in photochemical research, particularly used in dye-sensitized solar cells (DSSCs) and semiconductor energy transfer studies due to its strong light absorption and electron-donating capability.

Used as a redox probe in electrochemistry, Phenosafranine reversibly switches between oxidized and reduced forms, making it valuable in titrimetric analysis and biosensor research.

Phenosafranine is a well-known DNA intercalating dye, used in molecular biology and biophysics research to study DNA structure, nucleic acid binding, and drug-DNA interactions.

Used as a micelle probe dye to study micelle formation, surfactant behavior, and membrane dynamics in biochemistry.

Phenosafranine has historically been used as a photographic desensitizer, helping in specialty film and photo emulsion processes.

Phenosafranine is used to stain microorganisms, similar to Safranine, providing high contrast for microbial visualization.

Used in coloring paper, leather, and specialty fabrics, producing deep red-violet shades with strong fastness properties.
