Manufacturing Quality Control of 2,3-DIHYDROXYQUINOXALINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at ~254 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient HPLC-UV against qualified reference standards or threshold-based reporting. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone) by gas chromatography with flame ionization detection using headspace sampling. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, As, etc.) after acid digestion by inductively coupled plasma mass spectrometry with isotope dilution. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion at 700-800 C followed by precise weighing of ash. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder via Mie scattering theory using dispersed aerosol in air. |
| Organic Volatile Impurities (OVI) | GC-MS | Identifies and quantifies unknown volatile impurities using gas chromatography coupled with mass spectrometric detection. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume after standardized mechanical tapping per USP <616>. |
