Manufacturing Quality Control of 4-CHLORO-QUINAZOLINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by reversed-phase HPLC with UV detection, relative to main peak area using external standard or area normalization. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents by gas chromatography with flame ionization detection using a polar capillary column and headspace sampling. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol buffer system. |
| Heavy Metals | ICP-OES | Multi-element quantitative analysis of Pb, Cd, Hg, As, and other heavy metals after acid digestion, using plasma excitation and optical emission detection. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using an anion-exchange column with suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using controlled heating and visual observation of sample collapse. |
| Loss on Drying | Gravimetric Analysis | Measurement of mass loss after drying under specified temperature and vacuum conditions, indicating volatile content including moisture and solvents. |
| Residue on Ignition | Sulfated Ash Test | Quantification of non-volatile inorganic residue after high-temperature incineration following sulfuric acid treatment. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution by measuring angular variation in intensity of laser light scattered by suspended particles in liquid medium. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral molecules in solution, used to confirm stereochemical identity and detect enantiomeric impurities. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of hydrogen ion activity in a defined suspension of the compound in water using a calibrated glass electrode and reference electrode. |
