Industrial Applications of N-tert-butyl-L-serineisopropyl ester
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D and Manufacturing | Synthetic intermediate for peptide-based and small-molecule drugs, used to construct bioactive compounds containing serine residues | Used as a protected serine derivative in solid-phase or solution-phase peptide synthesis; the Boc group protects the amino functionality, and the isopropyl ester protects the carboxyl functionality; selective deprotection and coupling are achieved via acidolysis (e.g., TFA) to remove the Boc group, followed by base-mediated or hydrogenolytic cleavage of the isopropyl ester |
| Organic Synthesis | Chiral building block for asymmetric synthesis and total synthesis of complex natural products | Employed as a chiral auxiliary or structural unit in transformations such as Diels–Alder reactions, alkylation, and amidation; the isopropyl ester enhances lipophilicity to facilitate extraction and purification, while the Boc group remains stable under diverse metal-catalyzed and reductive conditions |
Manufacturing Quality Control of N-tert-butyl-L-serineisopropyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a reference standard using UV detection at specified wavelength. |
| Related Substances | HPLC-UV | Separation and quantification of impurities based on retention time and UV response relative to main peak. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents using flame ionization detection after gas chromatographic separation. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent where water reacts stoichiometrically to determine moisture content. |
| Heavy Metals | ICP-MS | Multi-element detection and quantification of trace metal contaminants via inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Residual Catalyst (Pd) | ICP-OES | Quantification of palladium residue by measuring atomic emission intensity after plasma excitation. |
| Optical Rotation | [alpha]D Measurement | Determination of specific rotation using polarimetry to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against defined standards under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size based on angular scattering pattern of laser light passing through dispersed sample. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity using calibrated glass electrode and pH meter in aqueous suspension. |
