Manufacturing Quality Control of N-alpha-Cbz-L-lysine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Chiral Purity | Chiral HPLC | Enantiomeric excess assessment using a chiral stationary phase to resolve L- and D-enantiomers, with UV detection. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Mass loss measured after drying under controlled temperature and time to determine volatile content including residual solvents and water. |
| Residual Solvents | GC-FID | Identification and quantification of common organic solvents (e.g., ethyl acetate, methanol) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensity. |
| Chloride Content | Potentiometric Titration | Determination of chloride ions using silver nitrate titrant and silver indicator electrode; endpoint detected by potential change. |
| Sulfated Ash | Gravimetric (550 C) | Residue mass after high-temperature incineration in presence of sulfuric acid, indicating inorganic impurities. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light at 20 C and 589 nm to confirm identity and enantiomeric integrity. |
| pH (1% aqueous solution) | pH Meter | Electrochemical measurement of hydrogen ion activity in a standardized aqueous suspension. |
| Related Substances | HPLC-UV | Detection and quantification of structurally similar impurities (e.g., deprotected lysine, di-Cbz species) using gradient HPLC-UV. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration with iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Microbial Limits | Membrane Filtration | Quantitative estimation of aerobic microorganisms and absence of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial methods. |
