Industrial Applications of Mpa(Trt)-OSu
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | C-terminal protecting reagent for solid-phase peptide synthesis (SPPS) | Used to temporarily protect the C-terminal carboxyl group in SPPS; deprotection is acid-sensitive via the tritylthio group and compatible with Fmoc strategy; this ester links to the resin and releases the free acid—or proceeds to further coupling—upon mild acid treatment (e.g., 1% TFA in DCM) |
Manufacturing Quality Control of Mpa(Trt)-OSu
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at characteristic wavelength. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by gradient HPLC separation and UV response. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, THF) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration with iodine-based reagent. |
| Heavy Metals | ICP-MS | Quantifies toxic elements (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and weighing. |
| Optical Rotation | Polarimetry | Determines specific rotation using sodium D-line light to confirm chiral integrity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range of solid-to-liquid transition using calibrated capillary method. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution using Mie scattering theory. |
| pH of Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in aqueous suspension using calibrated glass electrode. |
