Manufacturing Quality Control of 3-ETHOXYPHENYLBORONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and detection of impurities (e.g., residual phenol, boronic acid derivatives) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., ethanol, toluene, THF) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine and sulfur dioxide in pyridine/methanol medium to determine trace water content. |
| Heavy Metals | ICP-OES | Multi-element detection of toxic metals (e.g., Pb, Cd, Hg, Ni) after acid digestion, based on atomic emission intensity. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Residue mass after high-temperature incineration in presence of sulfuric acid, indicating inorganic impurities. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against defined standards under controlled lighting. |
| Bulk Density | ASTM D1895 | Measurement of mass per unit volume of freely settled powder using a calibrated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered light intensity patterns to determine size distribution of dry or dispersed particles. |
| Residual Boron Content | ICP-OES | Quantification of total boron after microwave-assisted acid digestion using boron-specific emission line. |
