Industrial Applications of Z-TYR-OBZL
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Used as a protected amino acid intermediate in peptide synthesis | Applied in solid-phase or solution-phase peptide synthesis to incorporate tyrosine residues while protecting the side chain and carboxyl group |
| Biochemical Research | Used to construct model peptides with defined sequences for studying proteolytic cleavage sites or protein–protein interactions | Coupled with other amino acids via standard condensation reactions (e.g., DCC/HOBt) |
| Organic Synthesis | Employed as a chiral building block in the construction of complex molecules | Deprotected to yield free tyrosine, enabling subsequent functionalization or cyclization reactions |
Manufacturing Quality Control of Z-TYR-OBZL
| 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 254 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., deprotected, hydrolyzed, or isomeric forms) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DMF, methanol, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol buffer system. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separation and conductivity-based detection of chloride ions after sample dissolution and filtration. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using a polarimeter at 20 degC with sodium D-line (589 nm) light. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile inorganic residue remaining after high-temperature ashing (600-750 degC) and cooling in a desiccator. |
| Appearance | Visual Inspection | Assessment of physical form, color, and clarity of crystalline powder under controlled white light against defined standards. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution by measuring angular variation in intensity of laser light scattered by dispersed particles. |
| Microbial Contamination | Membrane Filtration | Quantitative detection of aerobic microorganisms via filtration, membrane transfer to agar media, and colony enumeration after incubation. |
