Industrial Applications of N,N'-Di-Boc-L-lysine hydroxysuccinimide ester
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Lysine side-chain protecting reagent in peptide synthesis | Used selectively to protect the ε-amino group of lysine in solid-phase or solution-phase peptide synthesis, preventing side reactions; the Boc protecting group is subsequently removed via acidolysis (e.g., trifluoroacetic acid) |
| Biochemistry | Protein modification and crosslinking reagent | Conjugates primary amine-containing molecules (e.g., fluorescent probes, biotin) to lysine residues via NHS ester–amine reaction to form stable amide bonds |
| Diagnostics Development | Biomolecule labeling and conjugation | Serves as a linker to covalently attach reporter molecules (e.g., enzymes, dyes) to lysine sites on antibodies or other proteins during immunoassay or molecular probe preparation |
Manufacturing Quality Control of N,N'-Di-Boc-L-lysine hydroxysuccinimide ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound using reversed-phase HPLC with UV detection at 220 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities by gradient HPLC-UV, using relative response factors or external standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, THF, ethyl acetate) via headspace GC with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-OES | Quantifies metals (e.g., Fe, Cu, Ni, Pb) after acid digestion by optical emission spectroscopy at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Residual Tert-Butyl Alcohol | GC-FID | Detects residual t-BuOH by direct injection GC-FID with internal standard calibration. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation at 589 nm using sodium D-line to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Loss on Drying | Gravimetric Method | Measures mass loss after drying under controlled vacuum and temperature, indicating volatile content and solvent residues. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determines pH of 1% w/v suspension in water using calibrated pH electrode per USP <791>. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution using Mie scattering theory with automated dispersion. |
