| Industry | Application | Process |
|---|---|---|
| Biomedical | Fluorescent stain for detection of amyloid deposits | Staining of tissue sections, followed by fluorescence microscopy to visualize amyloid fibril formation |
| Biomedical | Biomarker detection in neurodegenerative disease research | Co-incubation with brain tissue or bodily fluid samples; fluorescence signal generation upon binding to β-sheet structures |
| Biotechnology | Fluorescent nucleic acid staining enhancer | Weak binding to DNA/RNA in specific buffer systems to enhance fluorescence signal for gel electrophoresis analysis |
| Environmental Monitoring | Tracer for amyloid-like substance contamination | Fluorescent labeling and quantitative detection of abnormal protein aggregates in water or biological samples |
| Pharmaceutical R&D | Probe for high-throughput screening of amyloid aggregation inhibitors | Use as a fluorescent reporter molecule in in vitro assays to monitor compound-mediated inhibition of protein aggregation |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies thioflavin T concentration based on absorbance at characteristic wavelength (e.g., ~412 nm) using molar absorptivity and Beer-Lambert law. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Measures mass loss after drying at specified temperature (e.g., 105 C) to determine volatile content including moisture and solvents. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Determines inorganic impurities by igniting sample at high temperature (e.g., 600–700 C) and weighing residual ash after sulfuric acid treatment. |
| Heavy Metals (as Pb) | AAS or ICP-OES | Quantifies total heavy metal content by atomic absorption or optical emission spectroscopy after acid digestion and calibration against lead standard. |
| Chloride Impurity | Potentiometric Titration | Measures chloride ions via titration with silver nitrate using silver indicator electrode; endpoint detected by potential change. |
| Sulfate Impurity | Gravimetric (Barium Sulfate Precipitation) | Precipitates sulfate as BaSO4, filters, dries, and weighs to calculate sulfate content based on stoichiometric equivalence. |
| pH of Aqueous Solution | Potentiometric (pH Meter) | Measures hydrogen ion activity in a standardized aqueous solution (e.g., 1% w/v) using calibrated glass electrode system. |
| Organic Volatile Impurities | GC-FID | Separates and quantifies residual solvents (e.g., ethanol, acetone) using gas chromatography with flame ionization detection. |
| Related Substances (Impurities) | HPLC-UV | Separates and detects structurally related compounds using reversed-phase HPLC with UV detection at appropriate wavelength. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior. |
| Water Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration using iodine-based reagent reacting stoichiometrically with water. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral molecules in solution to confirm identity and enantiomeric purity (if applicable). |
