Industrial Applications of Z-D-ALA-NH2
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Chiral drug synthesis intermediate for preparing D-alanine derivative active pharmaceutical ingredients | Used as an Nα-carbobenzyloxy (Cbz) protecting group for D-alanine in solid-phase peptide synthesis; removed via hydrogenolysis prior to subsequent coupling reactions |
| Organic Synthesis | Model substrate or ligand precursor in asymmetric catalysis and chiral resolution studies | Applied in constructing chiral catalyst ligand frameworks or employed as a chiral auxiliary in asymmetric alkylation, acylation, and related transformations |
Manufacturing Quality Control of Z-D-ALA-NH2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Optical Rotation | [a]D Measurement | Measures specific rotation of chiral compound in solution using sodium D-line light to confirm stereochemical identity. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) by inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines acidity/basicity of saturated aqueous suspension using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Identifies purity and identity by observing temperature range of solid-to-liquid phase transition. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension using angular scattering pattern of laser beam. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
