Description
Fluorescein sodium salt is a disodium salt of fluorescein and a noted pH sensitive fluorophore. Fluorescein sodium salt has been utilized in studies as a drug model, as a penetrating dye and also as a fluorescein tracer. Fluorescein sodium salt has also been used in vitro to quantify root dentin demineralization. Additional reported uses include microscopy, as a gain medium in dye laser use and to detect latent blood stains in vitro. Solubility :Soluble in water (500 g/l) at 20° C, ethanol (slightly soluble),Insoluble in benzene, chloroform, ether. Soluble in glacial acetic acid; also soluble in alkal i hydroxides or carbonates with a bright green fluoresence appearing red by transmitted light.
