Manufacturing Quality Control of 4,5-DIFLUORO-2-METHOXYPHENYLBORONIC 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 residual solvents (e.g., methanol, THF, toluene) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-MS | Quantitative determination of elemental impurities (e.g., Pb, Cd, Ni, Pd) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions after aqueous extraction and filtration; quantified against NaCl calibration standards. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 600-700 C followed by weighing of non-volatile inorganic residue after treatment with sulfuric acid. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against defined reference standards. |
| Residue on Ignition | Gravimetric Analysis | Determination of non-volatile inorganic residue after ignition at 700-800 C; reported as weight percent. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine D10, D50, D90 values per ISO 13320. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode following equilibration. |
