Industrial Applications of N'-Fmoc-L-lysine
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Intermediate for peptide synthesis | Used in solid-phase peptide synthesis (SPPS) as a lysine derivative with side-chain protection, providing an Fmoc-protected ε-amino group to facilitate subsequent coupling reactions |
| Pharmaceutical R&D | Development of antitumor drugs and targeted formulations | Introduced as a functionalized amino acid building block in the construction of peptide-based therapeutics or antibody–drug conjugates (ADCs) |
| Chemical Synthesis | Functional group modification of peptide molecules | Enables incorporation of modifiable lysine residues into peptide chains via Fmoc deprotection and coupling reactions, supporting crosslinking, labeling, or conjugation |
| Biomaterials | Design of functional biomaterials (e.g., nanocarriers) | Applied in synthesizing peptide-modified materials with targeting functionality to enhance biocompatibility or target specificity |
| Molecular Probes | Synthesis of fluorescently labeled or peptide-based probes | Used as a starting material to construct peptide probes bearing reporter or recognition groups for applications in bioimaging and detection |
Manufacturing Quality Control of N'-Fmoc-L-lysine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 265 nm, comparing peak area to a certified reference standard. |
| Chiral Purity | Chiral HPLC | Separation of L- and D-enantiomers on a chiral stationary phase, with UV detection to determine enantiomeric excess. |
| Residual Solvents | GC-FID | Detection and quantification of common solvents (e.g., DMF, DCM, methanol) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration with iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and plasma excitation. |
| Residual Fmoc Chloride | GC-MS | Identification and quantification of unreacted Fmoc-Cl impurity by gas chromatography coupled with mass spectrometry. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., diketopiperazine, deprotected lysine) using gradient HPLC. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after controlled heating under vacuum or nitrogen to determine volatile and moisture content. |
| pH (1% w/v aqueous solution) | Potentiometric Titration | Measurement of hydrogen ion activity in aqueous suspension using calibrated pH electrode. |
| Specific Optical Rotation | Polarimetry | Determination of chiral compound concentration and enantiomeric identity via rotation of plane-polarized light at 589 nm. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to derive volume-based particle size distribution. |
| Microbial Contamination | Membrane Filtration | Quantitative recovery of viable aerobic microorganisms from solution via filtration, followed by incubation on nutrient agar. |
