Fluorescein 1.Photo: 2.Properties:Orange or red powder, solve in hot alcohol, acetic acid and lye, insolve in water. 3. Requirment Results Molecular Formula C*0H*2O5 Melting Point ******1oC Maximal absorption wave length ******3 nm Quality absorption coefficient ≥**0 L/***** Solubility in alcohol passes test Sensitivity test passes test sulfated ash, percent ≤0.3 Loss on drying, percent ≤5.0 4.Describe: 1)The use of fluorescein-dipalmitoylphosphatidylethanolamine for measuring pH-changes in the internal compartment of phospholipid vesicles. 2)Fluorescein is a fluorophore commonly used in microscopy, in a type of dye laser as the gain medium, in forensics and serology to detect latent blood stains, and in dye tracing. Fluorescein has an absorption maximum at **4 nm and emission maximum of **1 nm (in water). The major derivative is Fluorescein isothiocyanate (FITC)
