Manufacturing Quality Control of Z-D-GLN-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies CBZ-D-GLN by reversed-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., CBZ-Gly, deamidated products) using gradient HPLC with UV detection. |
| Optical Rotation | [alpha]D | Measures specific optical rotation in aqueous solution using a polarimeter to confirm chiral integrity and enantiomeric purity. |
| Residual Solvents | GC-FID | Quantifies residual solvents (e.g., methanol, ethyl acetate, DMF) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water content via coulometric or volumetric titration using iodine-based redox reaction in anhydrous medium. |
| Heavy Metals | ICP-MS | Measures total heavy metal content (Pb, Cd, Hg, As, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue after high-temperature incineration of sample followed by weighing of the cooled ash. |
| pH (1% w/v solution) | Potentiometric Titration | Measures hydrogen ion activity in aqueous solution using calibrated pH electrode and standardized buffer references. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution by measuring angular variation in laser light scattering from dispersed particles in liquid medium. |
| Microbial Enumeration | Membrane Filtration | Quantifies aerobic mesophilic microorganisms by filtering sample through sterile membrane, culturing on TSA, and counting colonies. |
| Endotoxins | LAL Assay | Detects bacterial endotoxins using Limulus amebocyte lysate reagent, based on enzymatic clotting cascade triggered by endotoxin. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after ignition at 700-800 C, expressed as percentage of original sample weight. |
