Manufacturing Quality Control of 2-Bromo-9,9-diphenylfluorene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by retention time and UV absorbance relative to a reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents by gas chromatographic separation and flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water via coulometric or volumetric titration with iodine-based reagent. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) by mass spectrometric detection of elemental ions. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride anions using suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to assess chiral purity or identity. |
| Appearance | Visual Inspection | Evaluates physical state, color, and presence of foreign particles under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles by measuring angular scattering of laser light. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of a powder sample in a graduated cylinder. |
