Industrial Applications of BOC-L-TYROSINE ETHYL ESTER
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Intermediate for peptide synthesis | Used as a protected amino acid to incorporate tyrosine residues in solid-phase or solution-phase peptide synthesis; the amino group is protected by tert-butoxycarbonyl (Boc), and the carboxyl group is protected as an ethyl ester |
| Biochemistry | Synthesis of biologically active peptides | Applied in the preparation of hormones, enzyme inhibitors, or other pharmacologically active peptides via deprotection and coupling reactions into peptide chains |
| Organic Synthesis | Building block for constructing complex molecular structures | Employed as a chiral synthon in organic synthetic routes, participating in amide bond formation reactions for total synthesis of natural products |
Manufacturing Quality Control of BOC-L-TYROSINE ETHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., ethyl acetate, toluene, methanol) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent where water reacts stoichiometrically to determine trace moisture content. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using a polarimeter at 20 °C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-MS | Quantitative determination of toxic elements (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Residual Palladium | ICP-OES | Post-digestion analysis by inductively coupled plasma optical emission spectrometry to detect residual Pd from catalytic hydrogenation steps. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs under controlled heating rate. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under specified vacuum/temperature conditions to assess volatile and moisture content. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to calculate particle size distribution in dry powder form. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and absence testing for specified pathogens per USP <61> and <62>. |
