Manufacturing Quality Control of 3-Iodo-9H-carbazole
| 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 to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities by retention time and UV response relative to the main peak. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using capillary GC with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Determines trace metal contaminants (e.g., Pb, Cd, Hg) by plasma ionization and mass spectrometric detection of elemental isotopes. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and weighing of residual non-volatile matter. |
| 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 specified viewing conditions. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after ignition with sulfuric acid treatment to convert metals to sulfates, followed by weighing. |
| Specific Optical Rotation | Polarimetry | Measures degree of rotation of plane-polarized light caused by chiral centers in solution at specified concentration and wavelength. |
| Bulk Density | USP <616> Method I | Determines mass per unit volume of powder in a graduated cylinder after controlled tapping, reflecting flow and packing behavior. |
