| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthetic intermediate for anticancer agents (e.g., alectinib, brigatinib) | Constructing carbon–carbon bonds via Suzuki–Miyaura coupling |
| Pharmaceuticals | Synthetic building block for antiviral agents | Constructing complex pyridine-derived scaffolds |
| Organic Synthesis | Boronic ester reagent for aryl–aryl coupling reactions | Palladium-catalyzed cross-coupling reactions |
| Chemical R&D | Drug synthesis and structural modification | Serving as an electrophilic reagent for introducing pyridine rings |
| 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 by comparing retention times and peak areas to qualified reference standards or threshold-based reporting. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using gas chromatography with flame ionization detection against calibration curves. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in a controlled electrochemical or chemical system. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) by atomizing the sample and detecting elemental ions via mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection relative to chloride standard solutions. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by ignition at 700-800 C and weighing residual non-volatile matter after cooling. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of bulk material against defined standards under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension or dry state by analyzing angular scattering pattern of laser light. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of powder in a standardized graduated cylinder after mechanical tapping per USP <616>. |
| Specific Optical Rotation | Polarimetry | Measures angle of rotation of plane-polarized light caused by chiral centers in solution using sodium D-line light source. |
