Manufacturing Quality Control of (S)-(+)-1-PHENYL-1,2-ETHANEDIOL 2-TOSYLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210-230 nm, comparing peak area to a certified reference standard. |
| Enantiomeric Excess (ee) | Chiral HPLC | Separates (R)- and (S)-enantiomers on a chiral stationary phase; ee calculated from peak area ratio of enantiomers. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., toluene, THF, methanol) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation in pyridine-methanol buffer. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion by inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Measures chloride ion concentration using suppressed conductivity detection after anion exchange separation. |
| Sulfate Impurity | Ion Chromatography | Quantifies sulfate ion via anion exchange chromatography with suppressed conductivity detection. |
| Acid Value | Acid-Base Titration | Determines free acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against a white background under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic residue after high-temperature ashing (500-600 C) followed by weighing of the ignited crucible. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in suspension using Mie scattering theory and optical detection of diffracted laser light. |
