Manufacturing Quality Control of 2-bromo-7-chlorosipro[fluorene-9,9'-xanthene]
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally related impurities via diode-array detection and peak area comparison against reference standards. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using flame ionization detection with headspace sampling and internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration based on iodine consumption in pyridine-methanol buffer. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pb, Cd, Hg) via mass spectrometric detection after acid digestion and dilution. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after anion exchange separation. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or foreign matter under controlled lighting. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume of freely settled and tapped powder using standardized cylinder and tapping procedure. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser beam passed through dispersed sample. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light through a solution of known concentration and path length. |
