Manufacturing Quality Control of N-CARBOBENZOXY-DL-PHENYLALANINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 210 nm, comparing peak area against a certified reference standard. |
| Optical Rotation | Polarimetry | Measurement of the angle of rotation of plane-polarized light induced by chiral CBZ-DL-phenylalanine in solution. |
| Loss on Drying | Gravimetric (105 C oven) | Determination of volatile content by measuring mass loss after drying at 105 C to constant weight. |
| Residue on Ignition | Gravimetric (sulfated ash) | Measurement of inorganic residue remaining after controlled ignition at 700-800 C following sulfuric acid treatment. |
| Heavy Metals (as Pb) | Colorimetric (thiourea method) | Visual or spectrophotometric comparison of sample color intensity with lead standards after reaction with thiourea in acidic medium. |
| Chloride Impurity | Argentometric Titration (Mohr method) | Titration with standardized silver nitrate solution; endpoint detected by formation of red-brown silver chromate precipitate. |
| Sulfate Impurity | Barium Sulfate Turbidimetry | Formation of barium sulfate precipitate in acidic medium; quantification via turbidity measurement at 420 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., CBZ-glycine, deprotected phenylalanine) using gradient HPLC-UV. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric determination of water based on iodine consumption in pyridine-methanol solvent system. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Measurement of hydrogen ion activity using calibrated glass electrode in a 1% w/v aqueous suspension. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution. |
| Microbial Contamination | Membrane Filtration + Culture | Quantitative recovery of viable microorganisms by filtration, followed by growth on nutrient agar under controlled incubation conditions. |
