Manufacturing Quality Control of Pyrazole-3-boronic 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 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 capillary GC with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in a controlled electrochemical or chemical system. |
| Heavy Metals | ICP-MS | Determines total elemental impurities (e.g., Pb, Cd, Hg, As) by plasma ionization followed by mass spectrometric detection with isotopic resolution. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride anions using suppressed conductivity detection after anion-exchange column separation. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate anions using suppressed conductivity detection after anion-exchange column separation. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C and subsequent weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube and controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized white light and against specified reference criteria. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume of freely packed powder, then after mechanical tapping, to assess flow and packing behavior. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser light passed through dispersed sample in liquid or air medium. |
