Industrial Applications of Z-LYS(BOC)-OH DCHA
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Lysine-protected amino acid monomer for solid-phase peptide synthesis (SPPS) | Used in Fmoc-based solid-phase peptide synthesis as an Nα-tert-butoxycarbonyl (Boc)-protected lysine derivative, with the side-chain ε-amino group stabilized as a dicyclohexylamine salt to enable selective deprotection and coupling; commonly applied in the synthesis of therapeutic peptides, vaccine antigen peptides, and diagnostic peptide reagents containing lysine residues |
Manufacturing Quality Control of Z-LYS(BOC)-OH DCHA
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-220 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., free lysine, Boc-deprotected species) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DCM, THF, MeOH) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generation to determine trace water content based on stoichiometric reaction with Karl Fischer reagent. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, Ni) after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Residual Dicyclohexylamine | GC-MS | Qualitative and quantitative analysis of dicyclohexylamine by gas chromatography coupled with mass spectrometric detection. |
| 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 observed as the temperature range at which solid-to-liquid phase change occurs under controlled heating. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode to assess salt stability and protonation state. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying under specified conditions (e.g., 60 C, 2 h, vacuum), indicating volatile content including residual solvents and moisture. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in dry powder using laser light scattering and Mie theory-based calculation. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial methods. |
