Manufacturing Quality Control of 4-Amino-8-bromo-2-chloroquinazoline
| 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-UV | Detects and quantifies structurally related impurities using gradient reverse-phase HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents by gas chromatography with flame ionization detection against certified standards. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration based on iodine consumption in pyridine-methanol medium. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, Ni) by mass spectrometric detection after acid digestion. |
| Chloride Content | Potentiometric Titration | Measures chloride ions using silver nitrate titrant with silver/silver chloride indicator electrode. |
| Bromide Content | Ion Chromatography | Separates and quantifies bromide anions using suppressed conductivity detection after ion exchange separation. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration under controlled white light. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume of powder in a graduated cylinder after standardized mechanical tapping. |
