Manufacturing Quality Control of 9,9-Dimethyl-2-iodofluorene
| 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. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol medium. |
| Heavy Metals | ICP-MS | Determines trace metal contaminants (e.g., Pb, Cd, Hg, As) by plasma ionization and mass spectrometric detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube and controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized white light and against reference standards. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume of freely settled and tapped powder using standardized cylinder and tapping mechanism. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral centers in solution using sodium D-line source. |
