Manufacturing Quality Control of 4-Nitrophenylboronic 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 detection of impurities (e.g., 4-nitroaniline, 4-nitrophenol, boronic acid derivatives) using gradient HPLC-UV with relative response factor correction. |
| Residual Solvents | GC-FID | Identification and quantification of residual solvents (e.g., methanol, ethyl acetate, toluene) by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Volumetric titration with iodine-based reagent where water reacts stoichiometrically to determine trace moisture content. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element determination of heavy metals (Pb, Cd, Hg, As, Cr) after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after anion exchange separation. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by sulfuric acid treatment and final weighing of inorganic residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles or discoloration against defined standards under controlled lighting. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension (10 mg/mL) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to calculate volume-based particle size distribution. |
| Bulk Density | Graduated Cylinder Method | Mass per unit volume determined by gently pouring sample into a calibrated cylinder and measuring settled volume. |
