Manufacturing Quality Control of H-D-ALA-OBZL P-TOSYLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., methanol, ethyl acetate) against calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other heavy metals after acid digestion, using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate ions using suppressed conductivity detection following sample dissolution and filtration. |
| Residue on Ignition | Gravimetric Analysis | Weighing of inorganic residue remaining after high-temperature ashing (700-800 C) of a weighed sample. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Direct measurement using calibrated pH electrode in a saturated aqueous suspension or defined dilution. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using controlled heating and visual observation. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed sample via light scattering pattern to derive volume-based particle size distribution. |
