Manufacturing Quality Control of 9,9'-spirobi[fluoren]-2-amine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at characteristic wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV or HPLC-MS | Separates and detects structurally related impurities (e.g., mono-amino, diarylamine by-products) via retention time and spectral matching. |
| Residual Solvents | GC-FID | Quantifies volatile organic solvents (e.g., toluene, DMF, THF) using flame ionization detection with headspace sampling and internal standard calibration. |
| Heavy Metals (Pb, Cd, Hg, Cr, As) | ICP-MS | Measures trace metal concentrations after acid digestion by detecting elemental isotopes with high sensitivity and multi-element capability. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines water via electrochemical generation of iodine reacting stoichiometrically with water in anhydrous medium. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determines inorganic ash content by weighing sample before and after high-temperature incineration. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension based on angular scattering intensity of laser light. |
| Bulk Density | ASTM D1895 Method A (Tapped Density Tester) | Determines mass per unit volume of powder under standardized tapping conditions to assess flow and packing behavior. |
