Manufacturing Quality Control of 2-Chloro-3-pyridylboronic acid
| 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 starting materials, by-products) using gradient HPLC-UV with relative response factors or external standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Heavy Metals (Total) | ICP-OES | Quantifies total heavy metals (Pb, Cd, Hg, As, etc.) after acid digestion by measuring atomic emission intensities at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Residual Palladium | ICP-MS | Detects trace palladium catalyst residues with high sensitivity and selectivity following microwave-assisted acid digestion. |
| 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 presence of foreign particles under controlled white light against established reference standard. |
| Loss on Drying | Gravimetric Method | Measures weight loss after drying under specified temperature and vacuum conditions to determine volatile content. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dry powder using Mie scattering theory applied to laser light diffraction patterns. |
