Industrial Applications of Z-PHE-OSU
| Industry | Application | Process |
|---|---|---|
| Peptide Synthesis | Used to protect the amino group of amino acids during peptide chain assembly, yielding N-terminal benzyloxycarbonyl (Z)-protected peptide fragments | Reacts with free amino groups in solid-phase or solution-phase peptide synthesis to introduce the protecting group |
| Pharmaceutical R&D | Serves as an intermediate in the synthesis of peptide-based drugs, enabling construction of precursor molecules with defined amino acid sequences | Acts as an electrophilic reagent in activated esterification reactions for coupling with target molecules |
| Biochemistry | Used in protein conjugation and modification studies to label amino groups on proteins | Undergoes acylation with proteins or macromolecules in aqueous or organic buffered systems |
| Polymer Materials | Employed in the synthesis of functionalized polymers, incorporating amino acid structures into polymer side chains or end groups | Participates in graft copolymerization as a functional monomer or modifying agent |
| Organic Synthesis | Functions as an activated form of carboxylic acid, serving as a coupling reagent in esterification or amidation reactions | Reacts with alcohols or amines under basic catalysis to yield corresponding esters or amides |
Manufacturing Quality Control of Z-PHE-OSU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., hydrolysis products, residual starting materials) relative to main peak using gradient elution. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., DMF, dichloromethane, methanol). |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using a polarimeter at 20 °C with sodium D-line (589 nm) to confirm chiral integrity. |
| Residual Metals (e.g., Pd, Ni, Fe) | ICP-MS | Quantification of trace metal catalysts and process-related metals after acid digestion and nebulization into plasma. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions eluted from an anion-exchange column after sample dissolution. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under controlled temperature and vacuum to determine volatile and moisture content. |
| pH of Solution | Potentiometric pH Measurement | pH determination of a defined aqueous or aqueous-organic solution using a calibrated glass electrode. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled lighting against established specifications. |
| Microbial Limits | Membrane Filtration and Culture | Enumeration of aerobic microorganisms via filtration, membrane transfer to agar media, and incubation followed by colony counting. |
