| Peptide Synthesis | Used to synthesize peptide derivatives containing hydroxy-bearing amino acids | Serves as a side-chain modification precursor; introduced into the peptide chain via deprotection and coupling reactions |
| Agrochemical Intermediates | Used to synthesize active pharmaceutical ingredients with specific molecular structures | Functions as a functionalized alcohol intermediate in cyclization or condensation reactions to construct heterocyclic frameworks |
| Polymer Materials | Used to prepare functional monomers or crosslinkers | Reacts via its hydroxyl group with isocyanates and other reagents to form polyurethane-based polymers |
| Fine Chemicals | Used in the synthesis of fragrances, dyes, and catalyst ligands | Acts as a multifunctional scaffold bearing both nitrogen and hydroxyl groups, participating in metal coordination or esterification reactions |
Manufacturing Quality Control of (S)-(-)-2-(Boc-Amino)-1,4-butanediol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Enantiomeric Purity | Chiral HPLC | Separates (R)- and (S)-enantiomers on a chiral stationary phase and calculates enantiomeric excess from peak area ratio. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration using iodine generated in situ via electrochemical reaction with water. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., THF, EtOAc, MeOH) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Detects trace metal impurities (e.g., Pd, Ni, Fe) by plasma ionization and mass spectrometric quantification against calibration standards. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and suppressed conductivity detection. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid or solution against established reference standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measures angle of rotation of plane-polarized light induced by chiral compound in solution, reported as [alpha]D value. |
| Residual Boc Protecting Group | HPLC-UV | Quantifies unreacted or cleaved Boc acid derivatives by reversed-phase HPLC with UV detection and relative response factor correction. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to culture media, incubation, and colony enumeration per Ph. Eur. 2.6.12. |
