Manufacturing Quality Control of Dibenzothiophene-3-boronic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene) via gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against standard reference. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume of freely settled and tapped powder sample. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution by measuring angular variation in laser light scattering. |
| Boron Content | ICP-OES | Quantifies total boron after alkaline fusion or acid digestion using inductively coupled plasma optical emission spectroscopy. |
