Industrial Applications of Z-PRO-OSU
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Protecting group in peptide synthesis for temporary protection of proline residues | Used in solid-phase or solution-phase peptide synthesis; amino groups protected with N-carbobenzyloxy (Cbz) and subsequently deprotected via hydrogenolysis |
| Biochemistry | Protein modification and crosslinking reagent for conjugating molecules or labeling biomolecules | Reacts with amino groups to form amide bonds, commonly applied in protein–protein or protein–small molecule conjugation |
| Materials Science | Preparation of functionalized polymeric materials (e.g., peptide-based hydrogels or drug delivery carriers) | Employed as a monomer or crosslinker in polymerization reactions |
| Research Reagents | Organic synthesis intermediate for constructing complex molecules (e.g., natural products or drug analogues) | Introduced into target molecules via condensation of its active ester with amines to incorporate proline functionality |
Manufacturing Quality Control of Z-PRO-OSU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., N-Cbz-L-proline, NHS, hydrolysis products) relative to main peak using gradient elution. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual solvents (e.g., DMF, DCM, ethyl acetate) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific optical rotation using a polarimeter at 20 degrees C and sodium D-line (589 nm) to confirm chiral integrity. |
| Heavy Metals | ICP-MS | Quantitative determination of elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Residual Catalysts (Pd) | ICP-OES | Quantification of palladium residues after microwave-assisted acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs, indicating purity and identity. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying under controlled vacuum and temperature, reflecting volatile content and residual solvents. |
| pH of Solution | Potentiometric pH Measurement | pH measurement of a standardized aqueous or aqueous-organic solution using calibrated pH electrode. |
| Microbial Contamination | Membrane Filtration | Quantitative recovery and enumeration of aerobic microorganisms from sample solution via filtration, incubation, and colony counting. |
