Industrial Applications of FMOC-D-LYS(ALOC)-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Amino acid protecting group for peptide synthesis | In solid-phase or solution-phase peptide synthesis, the α-amino group of lysine is protected with N-(9-fluorenylmethoxycarbonyl) (Fmoc), while its side-chain ε-amino group is protected with N-(allyloxycarbonyl) (Alloc), enabling selective deprotection and stepwise coupling |
Manufacturing Quality Control of FMOC-D-LYS(ALOC)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 260-280 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., DMF, DCM, methanol) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction with iodine and sulfur dioxide. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific optical rotation using a polarimeter at specified temperature and concentration to confirm chiral integrity and enantiomeric purity. |
| Residual Metals (e.g., Pd, Ni, Fe) | ICP-MS | Multi-element quantification after acid digestion using inductively coupled plasma mass spectrometry with isotopic detection and internal standard correction. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying under controlled temperature and vacuum conditions, indicating volatile and moisture content. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in suspension using Mie scattering theory and calibrated optical models. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of pH in a defined aqueous suspension using a calibrated glass electrode and reference electrode. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and absence testing for specified pathogens using culture-based membrane filtration and incubation. |
| Residual Allyl Alcohol | GC-FID | Targeted quantification of allyl alcohol (a potential degradation product) by headspace GC-FID using external calibration. |
