Molecular Weight: 332.31
Product description:1. The adsorption indicator. REDOX indicator. Fluorescent photometric analysis of sulfur ions. Titration of chlorine, bromine and iodine. Fluorescein is luminescent material matrix. Make many creatures have fluorescent substances. Its forming complexes and ATP (adenosine of fluorescein), and then combined with fluorescence enzyme uciferase (1). Activation of fluorescein luminous oxidation process. The reaction used for detection of living creature, or to make quantitative analysis of low degree of bacterial contamination. For example, measured by fluorescence photometer. 2. Used as fluorescent indicator adsorption for precipitation titration determination of Cl -, Br - and I - and SCN - silver halide. Also used as a fluorescence tracer acid-base titration, PH 4.0 (green) to 6.6 (green). 3. Used as a indicator of chemical analysis, biological stain and cosmetic colorants.
