Industrial Applications of Z-D-PHG-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Key chiral intermediate for synthesizing β-lactam antibiotics (e.g., cephalosporins and penicillin derivatives) | Prepared via asymmetric synthesis or chiral resolution; used to construct side-chain structures in antibiotic molecules |
| Pharmaceuticals | Amino acid derivatives employed as protecting groups in peptide synthesis | Carbobenzyloxy (Cbz) group protects the amino functionality during solid-phase or solution-phase peptide synthesis; deprotected after amide bond formation |
| Chemical Research | Chiral auxiliaries or chiral building blocks for organic synthetic methodology development | Used in asymmetric catalysis, cycloaddition reactions, and other transformations to construct complex molecules containing chiral centers |
Manufacturing Quality Control of Z-D-PHG-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3A. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., methanol, ethyl acetate, toluene) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-800 C followed by weighing of non-volatile inorganic residue after sulfuric acid treatment. |
