| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Identifies and quantifies impurities (e.g., 4-formylbenzeneboronic acid, bis-boronic acid dimers) via gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies residual solvents (e.g., methanol, THF, toluene) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine-based reagent, based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, As, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature ignition followed by weight difference of the residue. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange separation. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode and pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior. |
| Loss on Drying | Thermogravimetric Analysis | Quantifies volatile matter (e.g., solvent, moisture) by weight loss upon heating at 105 C under vacuum or nitrogen. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in suspension using angular scattering pattern of laser light. |
| Specific Optical Rotation | Polarimetry | Determines optical activity using sodium D-line light through a solution to assess chiral purity (if applicable as enantiomerically enriched form). |
