Manufacturing Quality Control of Cbz-L-arginine hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Cbz-L-arginine HCl content) | HPLC with UV detection | Quantification based on peak area comparison against certified reference standard using reversed-phase chromatography and UV absorbance at 220 nm. |
| Chiral Purity | Chiral HPLC | Separation of L- and D-enantiomers on a chiral stationary phase; enantiomeric excess calculated from peak area ratio. |
| Water Content | Karl Fischer titration | Electrochemical titration measuring water via reaction of iodine with sulfur dioxide in pyridine/methanol medium. |
| Residual Solvents | Gas Chromatography (GC-FID) | Separation and quantification of volatile organic solvents (e.g., ethyl acetate, methanol) using flame ionization detection. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion by plasma excitation and optical emission measurement. |
| Chloride Impurity | Potentiometric titration with silver nitrate | Titration based on formation of insoluble AgCl; endpoint detected by silver ion-selective electrode. |
| pH (1% aqueous solution) | pH meter measurement | Electrochemical measurement of hydrogen ion activity in a standardized aqueous solution at 25 C. |
| Related Substances | HPLC with gradient elution | Detection and quantification of structurally related impurities (e.g., Cbz-arginine, arginine HCl, de-Cbz product) using UV detection. |
| Loss on Drying | Gravimetric analysis (105 C, 2 h) | Mass loss measured after drying under controlled temperature and time to determine volatile and moisture content. |
| Residue on Ignition | Sulfated ash gravimetry | Weight of inorganic residue after high-temperature combustion following sulfuric acid treatment. |
| Microbial Limits | Membrane filtration and plate count | Enumeration of aerobic microorganisms and absence testing for specified pathogens per pharmacopeial methods. |
| Particle Size Distribution | Laser diffraction | Analysis of particle size distribution in dry powder form using light scattering principles. |
