Manufacturing Quality Control of 7-chloro-3,4-dihydroisoquinoline
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-DAD | Detects and quantifies impurities by HPLC with diode array detection, identifying peaks based on retention time and spectral match. |
| Residual Solvents | GC-FID | Measures volatile organic solvents using gas chromatography with flame ionization detection against internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) via inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Ion Impurity | Ion Chromatography | Separates and quantifies chloride anions using suppressed conductivity detection after eluent gradient separation. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity based on sharpness and agreement with reference value. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under controlled temperature and vacuum, reflecting volatile content and residual moisture. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral molecules in solution, confirming enantiomeric identity and purity. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Evaluates acidity/basicity by measuring hydrogen ion activity in a saturated aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension by analyzing angular variation in laser light scattering intensity. |
| Residue on Ignition | Gravimetric Ash Test | Quantifies inorganic residue remaining after high-temperature combustion in a muffle furnace, indicating non-volatile inorganic impurities. |
