| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV or UPLC-MS | Separation and identification of structurally related impurities (e.g., 2-methylbenzoboric acid, 5-methylbenzoboric acid, biphenyl derivatives) using gradient elution and UV or mass spectral detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., THF, toluene, methanol) against internal/external standards per ICH Q3C. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (Pb, Cd, Hg, As, Ni, Pd) after microwave-assisted acid digestion, achieving sub-ppt detection limits. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration (500–600 °C) followed by precise weighing of residual inorganic matter. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis by observing the temperature range over which solid-to-liquid phase change occurs under controlled heating rate. |
| Appearance and Color | Visual Inspection & Hazen/APHA Color Scale | Subjective assessment of physical state (crystalline powder) and quantitative color evaluation against platinum-cobalt standards. |
| Boron Content | ICP-OES | Quantification of total boron after alkaline fusion or acid digestion, measured via characteristic atomic emission lines (e.g., 249.773 nm). |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation and quantification of chloride anion using anion-exchange column and suppressed conductivity detection following aqueous extraction. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using Mie scattering theory to determine volumetric particle size distribution (D10, D50, D90). |
