| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Chiral intermediate in peptide drug synthesis, used to construct therapeutic peptides containing homoserine residues | Used as an N-terminal Boc-protected amino acid monomer in solid-phase or solution-phase peptide synthesis; incorporated into the peptide chain via deprotection and coupling reactions |
| Biochemical Research | Non-canonical amino acid probe for protein structure and function studies, enabling site-specific labeling | Employed in fluorescence labeling, crosslinking, or stable isotope labeling experiments following enzymatic or chemical modification |
| Organic Synthesis | Chiral building block for synthesizing β-hydroxy-α-amino acid derivatives and cyclic analogs | Transformed via selective hydroxyl protection/activation, oxidation, reduction, or cyclization to construct heterocyclic structures such as oxazolines and lactones |
| 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. |
| Chiral Purity | Chiral HPLC | Separation of L- and D-enantiomers on a chiral stationary phase with UV detection; enantiomeric excess calculated from peak areas. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent where water reacts stoichiometrically to determine trace moisture content. |
| Residual Solvents | GC-FID | Gas chromatographic separation followed by flame ionization detection; quantification against solvent-specific calibration curves. |
| Heavy Metals | ICP-MS | Multi-element detection of metallic impurities at sub-ppq levels using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; chloride quantified via calibration. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., Boc-deprotected, oxidation, or hydrolysis products) using gradient HPLC. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity in aqueous solution using calibrated glass electrode and pH meter. |
| Specific Optical Rotation | [alpha]D Measurement | Measurement of plane-polarized light rotation in solution at 589 nm; confirms chiral integrity and concentration-corrected identity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change; used for identity and purity screening. |
| Loss on Drying | Gravimetric Thermogravimetry | Mass loss measured after controlled heating under specified temperature and time to determine volatile content. |
| Residue on Ignition | Sulfated Ash Gravimetry | Mass of non-volatile inorganic residue remaining after high-temperature ignition in presence of sulfuric acid. |
