Manufacturing Quality Control of BOC-CYS(TBU)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, THF, ethyl acetate) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol medium. |
| Optical Rotation | [alpha]D Measurement | Measures specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni, Fe) by inductively coupled plasma mass spectrometry after acid digestion. |
| Residual Palladium | ICP-MS | Specific quantification of palladium residues from catalytic hydrogenation steps using ICP-MS after microwave-assisted digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration (500-600 C) followed by weighing of the ash. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using Mie scattering theory and laser diffraction optics. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
| pH of Aqueous Suspension | Potentiometric Measurement | Measures pH of a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode and meter. |
