Industrial Applications of DIIODOFLUORESCEIN

Industry Application Process
Medical Diagnostics Fluorescent dyes for ophthalmic examinations (e.g., corneal injury detection) Dissolved in saline or buffer solution and instilled into the eye; fluorescence is visualized under blue light illumination
Biomedical Research Cell staining and tracer agent Prepared as a solution at appropriate concentration for fluorescent labeling of live cells or tissue sections, followed by observation under a fluorescence microscope
Analytical Chemistry pH indicator (color transition range approximately pH 4.0–6.0) Dissolved in ethanol or aqueous solution and added to the sample; pH is determined based on color change
Materials Science Fluorescent probe for sensor development Immobilized on polymer matrices or nanomaterial surfaces to enable fluorescent response for detection of specific ions or molecules

Manufacturing Quality Control of DIIODOFLUORESCEIN

Detection Item Common Analytical Method Method Overview
Assay (Purity) HPLC-UV Quantitative determination based on peak area comparison with reference standard using reversed-phase chromatography and UV detection at 490 nm.
Related Substances HPLC-UV Separation and quantification of impurities by retention time and response relative to main peak under validated gradient conditions.
Moisture Content Karl Fischer Titration Volumetric titration using iodine, sulfur dioxide, and pyridine in methanol to determine water content via stoichiometric reaction.
Residue on Ignition Gravimetric Analysis Measurement of non-volatile inorganic residue after high-temperature ashing at 550-600 C.
Heavy Metals ICP-OES Multi-element detection of Pb, Cd, Hg, As, and other regulated metals after acid digestion and plasma excitation.
Chloride Impurity Ion Chromatography Separation and quantification of chloride anion using suppressed conductivity detection after aqueous extraction.
Iodine Content Potentiometric Titration with Sodium Thiosulfate Redox titration of liberated iodine (from alkaline hydrolysis) using thiosulfate and starch endpoint detection.
pH of Aqueous Solution pH Potentiometry Measurement of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode.
Solubility in Water Visual Inspection and Filtration Qualitative assessment of complete dissolution in specified volume of water at 25 C followed by filtration to detect insoluble matter.
Particle Size Distribution Laser Diffraction Analysis of scattered laser light intensity to determine volumetric particle size distribution in dispersed suspension.
Melting Point Capillary Melting Point Apparatus Determination of temperature range over which solid transitions to liquid phase under controlled heating rate.
Organic Volatile Impurities GC-FID Detection and quantification of residual solvents (e.g., acetone, methanol, DMF) using flame ionization detection after headspace sampling.
