| Industry | Application | Process Description |
|---|---|---|
| Pharmaceuticals | Pharmaceutical Intermediates | Used as a lysine derivative in the synthesis of peptide-based drugs and active pharmaceutical ingredients (APIs) |
| Chemical Synthesis | Organic Synthesis Reagent | Applied as a protected amino acid in solid-phase peptide synthesis to construct specific amino acid sequences |
| Biotechnology | Peptide Research | Used to prepare lysine-containing peptide chains for studies on protein structure and function |
| Materials Science | Functional Material Synthesis | Serves as a building block in the synthesis of functional polymers or nanomaterials with targeted properties |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Chiral Purity | Chiral HPLC | Separates enantiomers on a chiral stationary phase and quantifies L-isomer content relative to D-isomer using UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., THF, DMF, EtOAc) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water mass fraction via coulometric or volumetric titration using iodine-based redox reaction in anhydrous medium. |
| Heavy Metals | ICP-MS | Measures trace metal impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion by inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Quantifies chloride ion concentration using suppressed conductivity detection after anion exchange separation. |
| Residual Allyl Alcohol | GC-FID | Detects unreacted allyl alcohol by gas chromatography with flame ionization detection using internal standard calibration. |
| Residual BOC Anhydride | HPLC-UV | Quantifies residual di-tert-butyl dicarbonate by reversed-phase HPLC with UV detection at 205 nm. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid sample against standard white background under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary method per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light at 20 C and 589 nm to confirm chiral integrity and identity. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution using Mie theory scattering pattern analysis of dispersed particles. |
