Industrial Applications of FMOC-SER(BSI)-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Amino acid protecting reagent | Used for selective protection of the hydroxyl and amino groups of L-serine in peptide synthesis, with Fmoc as the amino-protecting group and TBDMS as the hydroxyl-protecting group |
| Biochemistry | Intermediate for solid-phase peptide synthesis | Serves as a building block in solid-phase or solution-phase peptide synthesis, facilitating subsequent deprotection and chain elongation |
| Organic synthesis | Organic synthesis intermediate | Introduces a protected serine unit into complex molecule syntheses, suitable for systems sensitive to reaction conditions |
Manufacturing Quality Control of FMOC-SER(BSI)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities using gradient HPLC with UV detection; identification and quantification relative to main peak. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on retention time and response factor calibration. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and pyridine in methanol to determine water content based on stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract using anion-exchange column and suppressed conductivity detection. |
| Residual Palladium | ICP-OES | Quantification of palladium catalyst residue after microwave-assisted acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection via capillary method observing onset and completion of solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and homogeneity against established reference standard under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Measurement of particle size distribution in suspension using Mie scattering theory and laser diffraction instrumentation. |
| Residual Fluorenylmethyloxycarbonyl (Fmoc) Group | HPLC-UV | Specific assay for incomplete deprotection or degradation products containing intact Fmoc moiety using isocratic HPLC-UV. |
