| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Synthesis of drug molecules | Reacted with various amines to construct new drug molecular frameworks |
| Materials Science | Preparation of functional materials | Used to synthesize materials with specific optical or electrical properties |
| Organic Synthesis | Construction of complex molecular scaffolds | Employed in palladium-catalyzed Suzuki coupling reactions to form carbon–carbon bonds |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual aryl halides, boronic acid, dimer) using gradient HPLC-UV with system suitability criteria. |
| Residual Solvents | GC-FID | Measures trace solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation in pyridine-free reagent. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after incineration at 700-800 C and weighing of the cooled crucible. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection and external calibration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against defined standards. |
| Specific Optical Rotation | Polarimetry | Measures optical activity in solution using sodium D-line light to confirm chiral integrity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution using Mie theory scattering pattern analysis of dispersed aerosol. |
| pH of Aqueous Suspension | pH Meter | Determines pH of 1% w/v suspension in water using calibrated pH electrode and temperature compensation. |
