Industrial Applications of Z-ALA-OSU
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Used as an amino acid derivative coupling agent to protect amines and activate carboxyl groups in peptide synthesis | Forms stable amide bonds via reaction of the N-hydroxysuccinimide ester with amines, enabling peptide chain elongation or protein modification |
| Biochemistry | Applied in site-specific protein modification and crosslinking studies | Reacts selectively with the ε-amino group of lysine residues in proteins under mild aqueous conditions for specific labeling |
| Diagnostics Reagents | Serves as a precursor for fluorescent or biotin labeling to prepare high-sensitivity probes | Couples N-Cbz-L-alanine N-hydroxysuccinimide ester with fluorescent dyes or biotin, followed by conjugation to target proteins |
| Pharmaceutical Intermediates | Used in synthesizing bioactive peptide drug precursors | Acts as a protected, activated amino acid unit in solid-phase or solution-phase peptide synthesis, participating in stepwise condensation reactions |
Manufacturing Quality Control of Z-ALA-OSU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., hydrolysis products, isomers) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, dichloromethane) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based reagent stoichiometry. |
| Optical Rotation | [alpha]D Measurement | Measures specific optical rotation using a polarimeter to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-OES | Quantifies elemental impurities (e.g., Pb, Cd, Ni) after acid digestion by inductively coupled plasma optical emission spectrometry. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Residual Catalyst (Pd) | ICP-MS | Detects trace palladium from coupling reactions using inductively coupled plasma mass spectrometry with isotope dilution. |
| pH of Solution | Potentiometric pH Measurement | Determines acidity/basicity of a standardized suspension (e.g., 1% w/v in water/isopropanol) using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Identifies melting range as a physical identity and purity indicator based on thermal transition behavior. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting against established reference standards. |
| Loss on Drying | Gravimetric Analysis | Measures volatile matter loss by weight difference before and after drying under specified temperature and vacuum conditions. |
