Manufacturing Quality Control of (S)-1,2,3,4-TETRAHYDROISOQUINOLINE-3-METHANOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-230 nm based on peak area comparison to reference standard. |
| Enantiomeric Excess (ee) | Chiral HPLC | Resolves (R)- and (S)-enantiomers on a chiral stationary phase; ee calculated from peak area ratio. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using gas chromatography with flame ionization detection against calibration standards. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Detects trace metals (e.g., Pb, Cd, Hg, Ni) by plasma ionization followed by mass spectrometric quantification. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column with suppressed conductivity detection. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities using gradient HPLC-UV against qualified reference standards. |
| Optical Rotation | [alpha]D Measurement | Determines specific rotation using sodium D-line light source; confirms chiral integrity and batch consistency. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature ignition followed by weighing of residual residue. |
| pH (1% w/v aqueous solution) | pH Meter | Measures hydrogen ion activity in aqueous solution using calibrated glass electrode system. |
