Manufacturing Quality Control of 3,5-DIFLUORO-4-METHOXY-PHENYLBORONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., THF, methanol, toluene) against calibrated standards. |
| 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 (Pb, Cd, Hg, As, etc.) after acid digestion, using inductively coupled plasma mass spectrometry for sub-pptr detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature incineration at 700-800 C, expressed as percentage weight loss. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against sodium chloride calibration curve. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change under controlled heating rate (1-2 C/min). |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of the solid sample against established reference standards under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering principles to calculate D10, D50, and D90 values. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 10 mg/mL in water) using calibrated pH electrode after equilibration. |
| Specific Optical Rotation | Polarimetry | Determination of chiral purity using sodium D-line light; rotation angle measured in a standardized cell path length and concentration. |
