| Materials Science | Building rigid π-conjugated scaffolds for thermally activated delayed fluorescence (TADF) materials | Paired with electron-accepting groups to design donor–acceptor (D–A) molecules enabling efficient reverse intersystem crossing (RISC) |
Manufacturing Quality Control of 3-bromo-11H-benzo[b]fluorene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-DAD | Detects and quantifies impurities based on retention time and UV spectral match against reference standards. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using capillary column gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies trace metal elements (e.g., Pb, Cd, Hg) by plasma ionization and mass spectrometric detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and precise weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized lighting and viewing conditions. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral molecules in solution at specified concentration and path length. |
| Bulk Density | USP <616> Method I | Determines mass per unit volume of freely settled powder using calibrated cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution by analyzing angular variation in laser light scattering from dispersed particles. |
