Manufacturing Quality Control of Z-D-LYS-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., N-Cbz-L-lysine, di-Boc derivatives) using gradient HPLC and UV detection. |
| Optical Purity (Enantiomeric Excess) | Chiral HPLC | Measures D-enantiomer excess by separation on a chiral stationary phase and UV detection, comparing retention times and peak areas. |
| Residual Solvents | GC-FID | Quantifies residual solvents (e.g., methanol, dichloromethane, toluene) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water content via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Measures total heavy metal content (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry for ultra-trace detection. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by ignition at 600 C and weighing the non-volatile residue after cooling in desiccator. |
| pH of Aqueous Solution | Potentiometric Titration | Determines pH of 1% w/v aqueous suspension using calibrated pH electrode and standardized buffer solutions. |
| Specific Optical Rotation | [alpha]D Measurement | Measures optical rotation at 589 nm using sodium D-line lamp in a polarimeter, reporting value per g/mL and dm path length. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering pattern of laser beam passing through dispersed sample. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtering solution through membrane, incubating on soybean-casein digest agar, and counting colony-forming units. |
| Chloride Impurity | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on anion-exchange column with carbonate eluent. |
