Manufacturing Quality Control of (R)-(-)-Glycidyl nosylate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Enantiomeric Excess (ee) | Chiral HPLC | Separation on chiral stationary phase with UV detection; ee calculated from peak area ratio of (R)- and (S)-enantiomers. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection; quantification against external calibration standards. |
| Water Content | Karl Fischer Titration | Volumetric titration using iodine-based reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration | Titration with standardized potassium hydroxide solution in isopropanol/toluene; endpoint detected potentiometrically. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion; detection based on mass-to-charge ratio of metal ions. |
| Residual Chlorides | Ion Chromatography | Separation on anion-exchange column with suppressed conductivity detection; quantified using chloride calibration curve. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified reference under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Specific Optical Rotation | [alpha]D Measurement | Measurement of rotation angle of plane-polarized light at 589 nm using sodium D-line lamp and temperature-controlled cell. |
| Organic Impurities (Related Substances) | HPLC-UV | Detection and quantification of structurally related impurities using gradient reverse-phase HPLC with UV detection. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after controlled ashing at 700-800 C; expressed as percentage of original sample weight. |
