Industrial Applications of N'-Cbz-L-ornithine
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Chiral intermediates for synthesizing antiviral agents (e.g., HIV protease inhibitors) and peptide-based therapeutics | Deprotection (e.g., catalytic hydrogenolysis with H₂/Pd-C) or coupling reactions (e.g., DIC/HOBt-mediated condensation) in inert solvents (e.g., THF, DCM) to introduce the target molecule |
| Peptide Synthesis | Temporary protection of the ornithine side-chain amino group to prevent side reactions | Used as an Nα-protecting group in solid-phase peptide synthesis (SPPS); the Cbz group stabilizes the α-amino group and is subsequently removed selectively |
| Biochemical Research | Preparation of isotopically or fluorescently labeled ornithine derivatives for metabolic pathway tracing | Selective functionalization (e.g., alkylation, acylation) following Cbz protection, followed by deprotection to yield functionalized ornithine probes |
Manufacturing Quality Control of N'-Cbz-L-ornithine
| 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 210 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., N-Cbz-ornithine diastereomers, deprotected ornithine, hydrolysis products) using gradient HPLC-UV. |
| Chiral Purity | Chiral HPLC | Enantioselective separation on a chiral stationary phase to determine L-enantiomer excess relative to D-ornithine or racemate. |
| Residual Solvents | GC-FID | Quantitative determination of Class 2/3 residual solvents (e.g., methanol, ethyl acetate, toluene) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, As, Hg, Ni) after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration at 700-800 C followed by weighing of residue. |
| Specific Optical Rotation | Polarimetry | Determination of chiral compound concentration and enantiomeric integrity by measuring rotation of plane-polarized light at 589 nm. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Direct measurement using calibrated glass electrode in a standardized aqueous suspension/solution. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine D10, D50, D90 values based on light scattering patterns. |
| Microbial Contamination | Membrane Filtration | Quantitative detection of aerobic microorganisms and absence of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial methods. |
| Loss on Drying | Thermogravimetric Analysis | Weight loss measurement after drying at 105 C under vacuum or nitrogen to determine volatile content including residual moisture and solvents. |
