Manufacturing Quality Control of N-PHTHALOYL-L-GLUTAMIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (PHT-Glutamic Acid Content) | Acid-Base Titration with NaOH | Quantifies free carboxylic acid groups by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Optical Rotation | [a]D Measurement using Polarimeter | Measures specific rotation at 20 C and 589 nm to confirm chiral purity and identity of L-isomer. |
| Heavy Metals (as Pb) | Colorimetric Sulfide Precipitation | Forms colored metal sulfide complexes in acidic medium; compared visually or spectrophotometrically against lead standard. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 600-700 C followed by weighing of residual material. |
| Chloride Impurity | Argentometric Titration (Mohr method) | Titration with silver nitrate using potassium chromate indicator to form AgCl precipitate. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 in acidic medium, followed by filtration, drying, and weighing. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical quantification of water based on iodine generation proportional to water content. |
| Related Substances (Impurities) | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase C18 column and UV detection at 210 nm. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode in a 1% w/v aqueous solution. |
| Loss on Drying | Thermogravimetric Weighing | Determines volatile content by weight loss after drying at 105 C for 2 hours under vacuum or air. |
| Iron (Fe) Content | Atomic Absorption Spectroscopy (AAS) | Quantifies iron by measuring absorbance of ground-state Fe atoms at 248.3 nm in an air-acetylene flame. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects and enumerates aerobic mesophilic microorganisms using sterile membrane filtration followed by incubation on soybean-casein digest agar. |
