| Pharmaceutical Industry | Chiral active pharmaceutical ingredient (API) synthesis | Asymmetric synthesis process for constructing chiral small-molecule drugs containing a D-lysine moiety, delivering defined stereochemical configuration. |
| Biochemistry | Biochemical reagent and protected amino acid | Laboratory-scale synthetic process for protein engineering, peptide fragment ligation, and structural modification studies. |
Manufacturing Quality Control of Z-LYS(BOC)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Chiral Purity | Chiral HPLC | Enantiomeric excess assessment using a chiral stationary phase and UV detection, resolving D- and L-isomers. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DMF, methanol) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water via iodine-sulfur dioxide reaction in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residual Chlorides | Ion Chromatography | Quantitative separation and detection of chloride ions using suppressed conductivity detection. |
| Related Substances | HPLC-UV | Detection and quantification of structurally similar impurities (e.g., deprotected or hydrolyzed forms) using gradient HPLC. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under controlled temperature and vacuum, indicating volatile content including residual solvents and moisture. |
| pH of Solution | Potentiometric Titration | Measurement of aqueous solution pH using calibrated glass electrode to assess acid/base balance and potential degradation. |
| Specific Optical Rotation | Polarimetry | Determination of optical activity using sodium D-line light to confirm identity and enantiomeric integrity. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size via light scattering pattern generated by dispersed particles in air. |
| Microbial Limits | Membrane Filtration | Quantitative recovery and enumeration of aerobic microorganisms using sterile filtration and agar culture incubation. |
