Manufacturing Quality Control of (R)-(+)-5,5',6,6',7,7',8,8'-OCTAHYDRO-1,1'-BI-2-NAPHTHOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with Chiral Column | Enantioselective separation and quantification using a chiral stationary phase, with UV detection at ~280 nm. |
| Optical Rotation | [α]D Measurement | Determines specific rotation at 589 nm (Na D-line) in specified solvent/concentration to confirm enantiomeric identity and purity. |
| Residual Solvents | GC-FID or GC-MS | Quantifies volatile organic solvents (e.g., toluene, THF, ethanol) based on retention time and peak area against calibrated standards. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Ni, Fe) after acid digestion, offering sub-ppt detection limits. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with sample moisture. |
| Related Substances (Impurities) | Chiral HPLC-UV | Separates and quantifies structurally similar impurities (e.g., racemate, des-hydroxy analogs) using chiral resolution and UV detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change under controlled heating rate. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700–800 °C) and weighing. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Quantifies chloride ions via anion-exchange separation and suppressed conductivity detection. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension based on angular scattering intensity of laser light. |
| pH (in aqueous suspension) | Potentiometric pH Measurement | Determines surface acidity/basicity by measuring hydrogen ion activity in a standardized aqueous slurry. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder using a calibrated cylinder and balance. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) | Quantifies volatile content (e.g., adsorbed water, solvents) by mass loss upon controlled heating (e.g., 105 °C, 2 h). |
