Manufacturing Quality Control of Dibenzo[b,e]thiepin-11(6H)-one
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorbance at specified wavelength using reverse-phase C18 column and calibrated standard. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally related impurities using diode array detection and retention time matching. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone) by flame ionization detection after headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) by mass spectrometric detection of elemental ions in acid-digested sample. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride anions using conductivity detection after suppressed anion exchange separation. |
| Sulfate Impurity | Turbidimetry | Measures sulfate as barium sulfate precipitate by light scattering intensity in acidic medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue by weight difference after high-temperature ashing at 700-800 C. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using calibrated capillary tube and controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring rotation angle of plane-polarized light in solution at specified concentration and wavelength. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles by measuring angular variation in laser light scattering pattern. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measures hydrogen ion activity in saturated aqueous suspension using calibrated glass electrode and reference electrode. |
