Manufacturing Quality Control of 9,9'-(5-bromo-1,3-phenylene)bis(9H-carbazole)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound peak area relative to calibrated standard using UV detection at characteristic wavelength. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally related impurities by retention time and spectral matching against reference standards. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents based on retention time and flame ionization response. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between iodine, sulfur dioxide, and water in anhydrous methanol medium. |
| Heavy Metals | ICP-MS | Detects trace metal contaminants (e.g., Pb, Cd, Ni) by mass-to-charge ratio after acid digestion and plasma ionization. |
| Chloride Impurity | 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 of sample. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration under controlled lighting. |
| Bulk Density | USP <616> Method I | Measures mass per unit volume of freely settled powder using standardized cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in intensity of scattered laser light. |
| Optical Rotation | Polarimetry | Measures specific rotation of plane-polarized light to detect chiral impurities or enantiomeric excess. |
