Manufacturing Quality Control of BOC-THR(ME)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 205 nm. |
| Chiral Purity | Chiral HPLC | Separation of enantiomers on a chiral stationary phase; L-isomer content determined by relative peak area. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water via iodine-sulfur dioxide reaction in pyridine/methanol medium. |
| Residual Solvents | GC-FID | Gas chromatographic separation followed by flame ionization detection; quantification against external standards. |
| Heavy Metals | ICP-MS | Multi-element detection of trace metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on mass-to-charge ratio. |
| Chloride Impurity | Ion Chromatography | Anion exchange separation with conductivity detection; quantified using chloride standard calibration. |
| Sulfate Impurity | Ion Chromatography | Anion exchange separation with conductivity detection; quantified using sulfate standard calibration. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., deprotected, hydrolyzed, or epimerized forms) using gradient RP-HPLC. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through solution; correlates with enantiomeric excess. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determination using calibrated glass electrode in aqueous solution at specified concentration and temperature. |
| Appearance | Visual Inspection | Assessment of color and clarity against water-white standard under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change; recorded as onset and range. |
