Manufacturing Quality Control of 7-Bromo-2-iodo-9,9-dimethyl-9H-fluorene
| 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 | Detects and quantifies structurally similar impurities by retention time and UV response relative to the main peak. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, toluene) using gas chromatography with flame ionization detection and external calibration. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, Ni) after acid digestion by measuring metal ion mass-to-charge ratios. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by ignition at 700-800 C followed by precise weighing of residual non-volatile matter. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| 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 foreign particles under controlled white light against standard references. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume of freely poured then tapped powder sample using standardized ASTM D1895 procedure. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles by measuring angular scattering pattern of laser beam passing through dispersed sample. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to detect chiral impurities or enantiomeric excess if applicable. |
