Manufacturing Quality Control of carbazol-4-one hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Identifies and quantifies impurities by comparing retention times and peak areas to qualified reference standards or threshold-based reporting. |
| Residual Solvents | GC-FID | Measures volatile organic solvents using gas chromatography with flame ionization detection, calibrated with standard solvent mixtures. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine generated in situ via reaction with water in a controlled electrochemical cell. |
| Heavy Metals | ICP-MS | Quantifies trace metals (e.g., Pb, Cd, Hg, As) by plasma ionization followed by mass spectrometric detection of elemental isotopes. |
| Chloride Content | Potentiometric Titration | Measures chloride ions using silver nitrate titrant with silver/silver chloride indicator electrode detecting endpoint potential change. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C and weighing residual non-volatile matter after cooling in desiccator. |
| pH of Solution | pH Meter Measurement | Measures hydrogen ion activity in aqueous suspension (1% w/v) using calibrated glass electrode pH meter under controlled temperature. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring angle of plane-polarized light rotation in solution using sodium D-line light source. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus with controlled heating rate. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dispersed suspension using angular scattering pattern of laser beam. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration after incubation. |
