Industrial Applications of Z-ALA-ALA-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Intermediate for peptide-based drug synthesis; used to construct dipeptide structural units | Employed as an N-terminal protected dipeptide building block in solid-phase peptide synthesis (SPPS) or solution-phase synthesis; incorporated into the target peptide chain via deprotection and coupling steps |
| Biochemical Research | Structural module for enzyme substrate, inhibitor, or probe design—particularly for studying protease specificity (e.g., dipeptidyl peptidases) | Used as a customized substrate in in vitro enzyme kinetic assays; enzymatic cleavage products analyzed by HPLC or mass spectrometry |
| Cosmetic R&D (Limited Application) | Potential skin penetration-enhancing peptide or active ingredient carrier (sparsely documented in literature; not a mainstream application) | Served as a small-molecule peptide precursor in transdermal delivery system studies following formulation optimization |
Manufacturing Quality Control of Z-ALA-ALA-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies Z-ALA-ALA-OH peak area against a calibrated standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., dipeptide isomers, hydrolysis products) via gradient HPLC separation and UV response. |
| Residual Solvents | GC-FID | Measures trace organic solvents (e.g., DMF, DCM, methanol) using gas chromatography with flame ionization detection and external calibration. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Optical Rotation | [alpha]D | Measures specific optical rotation using a polarimeter at 20 deg C with sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-MS | Quantifies trace heavy metals (Pb, Cd, Hg, As, Ni) after acid digestion using inductively coupled plasma mass spectrometry with isotopic detection. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection and external standard calibration. |
| Residual Palladium | ICP-OES | Measures palladium residue from coupling catalysts after microwave digestion using inductively coupled plasma optical emission spectroscopy. |
| pH (1% w/v aqueous solution) | pH Meter | Determines hydrogen ion activity in a standardized aqueous solution using a calibrated glass electrode pH meter. |
| Loss on Drying | Gravimetric Analysis | Measures volatile content by weight loss after drying at 105 deg C under vacuum for 2 hours. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering intensity of laser light passed through dispersed sample. |
| Microbial Contamination | Membrane Filtration | Detects aerobic bacteria, yeasts, and molds by filtering sample through membrane, culturing on appropriate media, and enumerating colony-forming units. |
