Manufacturing Quality Control of 9h-carbazol-3ylboronic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase chromatography with UV detection at 254 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities by retention time and peak area relative to main peak using validated gradient method. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) via headspace injection and flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing of the cooled crucible. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation of phase change. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized white light and against specified reference. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder using angular scattering pattern of laser beam passed through dispersed sample. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of powder after standardized mechanical tapping to simulate handling and storage conditions. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode and buffer standards. |
