Manufacturing Quality Control of 9-([1,1'-biphenyl]-3-yl)-3-broMo-9H-carbazole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound concentration using UV detection at optimal wavelength, calibrated against certified reference standard. |
| Related Substances | HPLC-UV/DAD or UPLC-MS | Separates and detects structurally related impurities (e.g., des-bromo, hydrolyzed, dimeric by-products) via retention time and spectral matching. |
| Residual Solvents | GC-FID | Quantifies volatile organic solvents (e.g., DMF, toluene, methanol) using flame ionization detection with headspace sampling. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pd, Ni, Cu from catalysis) via elemental mass spectrometry after acid digestion. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines water content electrochemically by iodine generation and stoichiometric reaction with water. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash residue after high-temperature incineration (700–800 °C) and weighing. |
| Melting Point | Differential Scanning Calorimetry (DSC) | Determines melting onset and range based on endothermic heat flow during controlled heating. |
| Optical Rotation | [α]D Measurement (Polarimetry) | Measures specific rotation at 589 nm to confirm chiral integrity (if applicable) or detect chiral impurities. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample to determine D10, D50, D90 values based on light scattering patterns. |
