Fluorescein Usage And Synthesis
Chemical Properties orange-red crystalline powder
Uses A fluorescent tracer used for many applications. It is used in ophthalmology as a tool in the diagnosis of corneal abrasions, corneal ulcers and herpetic corneal infections. It can attach to certain biologically active molecules, thus allowing biologists to target the fluorophore to specific proteins or structures within cells
Uses corneal trama indicator
Definition ChEBI: A xanthene dye that is highly fluorescent, detectable even when present in minute quantities. Used forensically to detect traces of blood, in analytical chemistry as an indicator in silver nitrate titrations and in microscopy.
General Description Yellow amorphous solid or orange-red crystals. Latter have greenish-yellow fluorescence by reflected light. Insoluble in water. Soluble in dilute aqueous bases. Very dilute alkaline solutions exhibit intense, greenish-yellow fluorescence by reflected light. Low toxicity. May be sensitive to prolonged exposure to light.
Air & Water Reactions Insoluble in water.
Reactivity Profile Fluorescein is incompatible with strong oxidizers. Also incompatible with acids, acid salts and salts of heavy metals. .
Fire Hazard Flash point data for Fluorescein is not available, but Fluorescein is probably combustible.
