Manufacturing Quality Control of 8-BROMO-2-CHLOROQUINAZOLINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification by retention time matching with reference standards or relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, toluene) using gas chromatography with flame ionization detection and external calibration. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration with iodine-based reagent; reaction stoichiometry enables precise water quantification. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection and external standard calibration. |
| Residual Palladium | ICP-OES | Measures palladium residue from catalytic steps after microwave-assisted acid digestion using inductively coupled plasma optical emission spectrometry. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid phase transition using calibrated capillary apparatus under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against white/black background under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dry powder form using Mie scattering theory applied to laser diffraction pattern analysis. |
| Bulk Density | USP <616> Tap Density Test | Determines mass per unit volume after standardized tapping of a known powder mass in a graduated cylinder. |
| Organic Volatile Impurities (OVI) | GC-MS | Identifies and quantifies non-specified volatile organic impurities using gas chromatography coupled with mass spectrometric detection and library matching. |
