Manufacturing Quality Control of DIBENZO(F H)QUINOXALINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase chromatography with UV detection at characteristic wavelength. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally similar impurities via diode array detection and peak spectral comparison. |
| Residual Solvents | GC-FID | Measures volatile organic solvents by gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Determines trace metal contaminants (e.g., Pb, Cd, Hg) using inductively coupled plasma mass spectrometry. |
| Chlorinated Impurities | GC-ECD | Detects chlorinated organic impurities via electron capture detection for high sensitivity to halogens. |
| Water Content | Karl Fischer Titration | Determines water by volumetric or coulometric titration using iodine-sulfur dioxide reaction in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Determines volatile content by weight loss after controlled heating under standard conditions. |
| Sulfated Ash | Gravimetric (500-600 C) | Quantifies inorganic residue after combustion and sulfuric acid treatment followed by high-temperature ignition. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension using angular scattering intensity of laser light. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder using standardized cylinder and funnel apparatus. |
| pH of Aqueous Suspension | pH Meter | Determines acidity/basicity of a defined suspension in purified water using calibrated glass electrode. |
