Industrial Applications of Z-SAR-OSU
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Amino acid protecting reagent | Used to protect the amino group of amino acids (Z-protecting group) to prevent undesired side reactions during peptide synthesis. |
| Biopharmaceuticals | Raw material for peptide synthesis | Applied as an activated ester in solid-phase or solution-phase peptide synthesis to facilitate peptide bond formation. |
| Biopharmaceuticals | Protein modification | Serves as a linker to incorporate sarcosine into proteins or peptide chains for labeling or functionalization. |
| Chemicals / R&D | Chemical reagent | Employed in the synthesis of other complex organic molecules or pharmaceutical intermediates. |
Manufacturing Quality Control of Z-SAR-OSU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-220 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., hydrolysis products, residual sarcosine, NHS) using gradient HPLC and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, THF, acetonitrile) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based reagent reacting stoichiometrically with water. |
| Residual N-Hydroxysuccinimide (NHS) | HPLC-UV | Quantifies unreacted NHS by reversed-phase HPLC with UV detection, leveraging its distinct retention time and absorbance. |
| Residual Sarcosine | HPLC-UV | Detects unreacted Z-sarcosine using HPLC-UV under acidic conditions to separate and quantify the free amino acid. |
| Heavy Metals | ICP-OES | Screens for toxic metals (Pb, Cd, Hg, As, Ni) after acid digestion by measuring elemental emission intensities at characteristic wavelengths. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on an anion-exchange column. |
| pH of Solution (5% w/v in water) | Potentiometric Titration | Measures hydrogen ion activity in aqueous suspension using calibrated pH electrode; reflects acid/base balance from residual reactants or degradation. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via comparison to literature value (~120-124 C). |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and absence of racemization during synthesis. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Determines volatile matter including residual solvents and moisture by weight loss after controlled heating under specified conditions. |
