Manufacturing Quality Control of 3,5-Dimethylisoxazole-4-boronic acid pinacol ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-230 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and peak area normalization. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., THF, MeOH, EtOAc) per ICH Q3C. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, Ni) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Residual Palladium | ICP-MS | Specific quantification of palladium residues from cross-coupling synthesis, following microwave-assisted acid digestion. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against chloride standard calibration. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against established reference standard under controlled lighting. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying sample at specified temperature (e.g., 60 C under vacuum) for fixed duration. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 10 mg/mL in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine volume-based particle size distribution (D10, D50, D90). |
