| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies 4-aminophenylboronic acid by retention time and UV absorbance against a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., aniline, boronic acid derivatives) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Measures trace organic solvents (e.g., methanol, THF, toluene) based on flame ionization response after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine generated electrochemically in pyridine-methanol medium. |
| Heavy Metals | ICP-OES | Quantifies total heavy metals (Pb, Cd, Hg, As, Ni) after acid digestion by atomic emission intensity at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange separation. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using suppressed conductivity detection after anion exchange separation. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (500-600 C) and weighing. |
| pH of Aqueous Solution | Potentiometric Titration | Measures hydrogen ion activity in a saturated aqueous suspension using a calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid phase transition using controlled heating and visual observation. |
