| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as an organic synthesis intermediate in the production of drug molecules, such as kinase inhibitors | Applied in Suzuki-Miyaura cross-coupling reactions |
| Materials Science | Used in the synthesis of organic optoelectronic materials, including conjugated polymers for OLEDs and OFETs | Applied in aryl–aryl coupling reactions |
| Chemical Research | Used as a boronate reagent in arylations for constructing complex organic molecules | Applied in transition metal-catalyzed C–C bond formation |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption relative to a reference standard using reverse-phase chromatography. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities based on retention time and peak area relative to main peak. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Heavy Metals | ICP-OES | Quantifies metal impurities (e.g., Pd, Ni, Fe) by atomic emission spectroscopy after acid digestion. |
| Residual Palladium | ICP-MS | Provides ultra-trace quantification of palladium catalyst residues using mass spectrometric detection. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| 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 controlled lighting conditions. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under specified temperature and vacuum to determine volatile content. |
| Residue on Ignition | Gravimetric Analysis | Quantifies inorganic ash content by high-temperature incineration followed by weighing of residual residue. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and absence of racemization. |
