Industrial Applications of Z-D-VAL-OSU
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Synthesis | Used as an amino acid protecting agent in peptide drug synthesis | Reacting with free amino groups to form stable carbobenzyloxy (Cbz) protecting groups, enabling selective protection of amino groups at specific positions during peptide synthesis and preventing unwanted side reactions. The Cbz protecting group is subsequently removed via hydrogenolysis or other suitable methods after completion of the target peptide chain assembly. |
| Biotechnology | Used as an amino acid modifier in protein engineering | Chemically modifying specific lysine residues in target proteins to alter their physicochemical properties or biological activity. This process typically involves direct addition of Cbz-D-valine N-hydroxysuccinimide ester to a solution containing the target protein, facilitating covalent bond formation under mild conditions. |
| Cosmetics | Added as a functional ingredient in skincare formulations | Used as a skin-conditioning agent to support improved skin condition. Dissolved in a suitable solvent and blended uniformly with other cosmetic ingredients at a defined ratio, followed by filtration and filling to produce the final product. |
Manufacturing Quality Control of Z-D-VAL-OSU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 220 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities by HPLC separation with UV detection, using relative response factors or external standardization. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, THF, ethyl acetate) via gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation in pyridine-free reagent. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation at 589 nm using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Residual Metals (e.g., Fe, Cu, Ni, Pb) | ICP-MS | Quantifies trace metal impurities after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measures pH of a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation. |
| Loss on Drying | Gravimetric Thermogravimetry | Measures weight loss after drying under specified temperature and vacuum conditions to assess volatile content. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder using Mie scattering theory applied to laser diffraction patterns. |
| Microbial Limits | Membrane Filtration & Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
