| Organic Electronics | Employed as emissive material or hole-transport layer material in organic light-emitting diodes (OLEDs) | Deposited uniformly onto substrates using techniques such as chemical vapor deposition or spin coating to form thin-film structures |
| Optoelectronic Materials | Applied as light-absorbing agents in optoelectronic conversion devices, e.g., solar cells | Incorporated into optoelectronic materials via solution-processing methods (e.g., spin coating, spray coating) or thermal evaporation to improve light absorption efficiency |
| Analytical Chemistry | Utilized as a fluorescent probe or label for biomedical assays | Immobilized on target analytes via covalent bonding or other means, enabling qualitative and quantitative analysis based on its fluorescence properties |
| Chemical Research | Served as a novel organic synthesis intermediate in the construction of complex organic compounds | Reacted in organic solvents through catalyzed addition, coupling, and related steps to yield target products |
Manufacturing Quality Control of 897921-59-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at characteristic wavelength based on peak area comparison to reference standard. |
| Related Substances | HPLC-DAD or HPLC-MS | Separates and detects impurities using gradient HPLC coupled with diode array or mass spectrometric detection for identification and quantification. |
| Residual Solvents | GC-FID | Measures volatile organic solvents by gas chromatography with flame ionization detection using headspace sampling and external calibration. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry for multi-element detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange column separation. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after combustion with sulfuric acid treatment and high-temperature incineration to constant weight. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per pharmacopeial standards. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference samples. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular variation in laser light scattering from dispersed sample in liquid or air. |
| Bulk Density | USP <616> Tap Density Method | Determines mass per unit volume after mechanical tapping of a known powder mass in a graduated cylinder to achieve reproducible packing. |
| Residual Palladium | ICP-OES | Quantifies palladium catalyst residue after microwave-assisted acid digestion using inductively coupled plasma optical emission spectroscopy. |
