Acid Red 94 CAS 632-69-9

What is Acid Red 94 CAS 632-69-9?

Acid Red 94 CAS 632-69-9 is a synthetic organic xanthene dye, chemically structured as a heavily halogenated (chlorinated and iodinated) fluorescein derivative formulated as a water-soluble sodium salt. Supplied as a bordeaux-red to red-brown crystalline powder, it dissolves readily in water to produce a distinct red solution. Unlike standard industrial commercial dyes, Rose Bengal functions as a potent photoactive sensitizer, capable of generating singlet oxygen upon exposure to specific light wavelengths. Its unique photochemical reactivity and specific biological binding properties make it an indispensable reagent for vital cell staining, veterinary ophthalmology, and targeted antimicrobial assays.

Specifications

Features

• Potent Photosensitizer – Generates reactive singlet oxygen upon targeted photoirradiation, making it highly effective for specialized photodynamic therapy research and light-dependent bio-assays.
• Highly Specific Vital Stain – Exhibits a strong, selective affinity for dead epithelial cells and localized mucus without penetrating intact intercellular spaces, ensuring precise clinical diagnostics.
• Strong Antimicrobial Properties – Demonstrates inherent biological activity, proving effective at inhibiting the growth of specific resilient pathogens, including methicillin-resistant Staphylococcus aureus (MRSA).

Applications

• Clinical & Veterinary Ophthalmology – Extensively utilized as a diagnostic vital stain to identify damaged corneal epithelium, keratoconjunctivitis sicca, and viral keratitis.
• Microbiological & Cellular Research – Serves as a highly reliable alternative to traditional Gram staining, and is broadly applied for staining cells, identifying fungi, and detecting amyloid accumulation.
• Advanced Materials & Photodynamic Therapy – Applied as a key component in the engineering of optical waveguides, color filters, and acts as an active photosensitizing agent in experimental targeted medical therapies.
