Manufacturing Quality Control of 9H-FLUORENE-9,9-DIMETHANOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities by separation on C18 column and UV absorbance, relative to main peak. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents using gas chromatography with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-OES | Determines total heavy metal content (e.g., Pb, Cd, Ni) by plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion with sulfuric acid treatment and high-temperature ashing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against standard reference under controlled lighting. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic residue after high-temperature ignition without sulfuric acid pretreatment. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode. |
