Manufacturing Quality Control of FMOC-ASP(OALL)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., diastereomers, hydrolysis/decomposition products) via gradient reverse-phase HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, DCM, THF) using gas chromatography with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine consumption in pyridine-methanol buffer. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-OES | Quantifies metallic impurities (e.g., Fe, Cu, Ni, Pb) after acid digestion by atomic emission spectroscopy. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Residual Palladium | ICP-MS | Detects trace palladium (from coupling catalysts) with high sensitivity using inductively coupled plasma mass spectrometry. |
| Particle Size Distribution | Laser Diffraction | Measures dry or wet dispersed particle size distribution based on light scattering patterns. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary method per USP <741>. |
| pH of Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in aqueous suspension or solution using calibrated glass electrode. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
