Manufacturing Quality Control of Phthaloyl-L- alanyl-L-glutamine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification via retention time matching and threshold-based reporting. |
| Residual Solvents | GC-FID | Measures residual organic solvents (e.g., methanol, acetone, DMF) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry. |
| Optical Rotation | [alpha]D Measurement | Measures specific optical rotation at 589 nm using sodium D-line to confirm chiral integrity and enantiomeric purity. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C followed by precise weighing of residual residue. |
| pH (1% w/v aqueous solution) | pH Meter | Measures hydrogen ion activity in a standardized aqueous solution using calibrated pH electrode and buffer reference standards. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample to determine volume-based particle size distribution using Mie scattering theory. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens (e.g., E. coli, S. aureus) by filtration, culture, and colony enumeration. |
| Endotoxin | LAL Assay | Detects bacterial endotoxins using Limulus amebocyte lysate reagent via kinetic turbidimetric or chromogenic reaction. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions after sample dissolution using suppressed conductivity detection with anion-exchange column. |
