Features:

• Fluorescence: Fluorescein sodium is highly fluorescent, emitting bright green light when illuminated with UV or blue light. This property makes it useful in various fluorescence-based applications.
• Solubility: It is highly soluble in water, which allows for easy preparation of aqueous solutions.
• Stability: Fluorescein sodium is relatively stable under normal conditions. However, it may degrade upon exposure to heat, light, or certain chemical agents.

Applications:

• Medical Diagnostics: Fluorescein sodium finds extensive use in ophthalmology for diagnostic purposes. It is used as a fluorescent dye for staining the cornea and conjunctiva to detect corneal abrasions, foreign bodies, and other eye surface irregularities.
• Angiography: It is employed in fluorescein angiography, a medical imaging technique used to visualize blood flow in the retina and choroid. In this application, it is injected intravenously, and the fluorescence helps to identify and assess abnormalities in blood vessels.
• pH Indicator: Fluorescein sodium can act as a pH indicator, exhibiting different emission colors depending on the pH of the solution. This property is utilized in pH measurement and monitoring systems.
• Fluorescence Microscopy: It is used as a fluorescent marker in microscopy techniques to visualize biological structures, such as cells or organelles, by labeling them with fluorescein sodium-conjugated antibodies or dyes.
