Manufacturing Quality Control of 2-Hydroxyphenylboronic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold reporting. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., methanol, THF, ethyl acetate) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent; water reacts stoichiometrically to determine trace moisture content. |
| Heavy Metals | ICP-MS | Multi-element quantitative analysis after acid digestion; detection at sub-ppt levels using mass spectrometry with isotope dilution or external calibration. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; quantified against chloride standard calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Sample incineration at 700-800 C followed by sulfuric acid treatment and final ash weighing to determine inorganic residue content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or via automated optical detection as solid converts to liquid; reported as onset and clear point range. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of solid sample under controlled white light against defined reference standards (e.g., white to off-white crystalline powder). |
| Residue on Ignition | Gravimetric Analysis | Ignition at 600-700 C to constant weight; mass of non-volatile residue expressed as percentage of original sample weight. |
| Organoboronic Acid Content | Acid-Base Back Titration | Hydrolysis of boronic acid group with mannitol to form stable complex, followed by titration with standardized NaOH using phenolphthalein indicator. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to calculate volume-based particle size distribution in dry or wet dispersion mode. |
