Manufacturing Quality Control of 170709-41-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, relative to a certified reference standard. |
| Enantiomeric Purity | Chiral HPLC | Separates (1S,2S) enantiomer from (1R,2R), (1S,2R), and (1R,2S) isomers using a chiral stationary phase and UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., toluene, ethyl acetate) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagent. |
| Heavy Metals | ICP-MS | Quantifies Pb, Cd, Hg, As, and other regulated metals after acid digestion using inductively coupled plasma mass spectrometry. |
| Residual Palladium | ICP-OES | Measures palladium content from catalytic hydrogenation steps using inductively coupled plasma optical emission spectroscopy. |
| Acid Value | Acid-Base Titration | Determines free acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Loss on Drying | Gravimetric Analysis | Measures volatile content by weight loss after drying at 105 C under vacuum for 2 hours. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution using Mie scattering theory and a laser diffraction particle size analyzer. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against a white/black background under controlled lighting. |
| Residual p-Toluenesulfonyl Chloride | GC-MS | Identifies and quantifies unreacted sulfonyl chloride impurity using gas chromatography coupled with mass spectrometry. |
