Manufacturing Quality Control of Z-ASP(OME)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by retention time and UV absorbance relative to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents based on retention time and flame ionization response. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) by mass-to-charge ratio after acid digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Optical Rotation | [alpha]D Measurement | Determines specific rotation using polarized light to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weight measurement. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in intensity of laser light scattered by dispersed particles. |
| Bulk Density | USP <616> Tap Density Test | Determines mass per unit volume after controlled tapping to assess powder flow and handling properties. |
