Manufacturing Quality Control of 9-(3,5-Dibromophenyl)-9H-carbazole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at characteristic wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., mono-bromo analogues, des-bromo carbazole) via gradient elution and peak area comparison. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, toluene, THF) using capillary column separation and flame ionization detection against calibrated standards. |
| Heavy Metals | ICP-MS | Determines trace metal contaminants (e.g., Pd, Ni, Fe, Cu) by plasma ionization and mass spectrometric detection with isotope dilution quantification. |
| Water Content | Karl Fischer Titration (Coulometric) | Quantifies water by electrochemical generation of iodine reacting stoichiometrically with water in anhydrous methanol-based electrolyte. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing (700–800 °C) and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid phase transition using calibrated digital apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against defined reference standards under controlled lighting. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid powder via angular scattering pattern analysis of laser beam passing through dispersed sample. |
| Bulk Density | ASTM D1895 Method A | Determines mass per unit volume of freely settled powder using standardized graduated cylinder and calibrated balance. |
| Organic Volatile Impurities (OVI) | GC-MS | Identifies and quantifies unknown or unexpected volatile organic impurities using mass spectral library matching and selected ion monitoring. |
| Optical Rotation | [α]D Measurement | Measures specific rotation at 589 nm using sodium D-line light source and temperature-controlled cell for chiral purity assessment (if applicable). |
