Manufacturing Quality Control of DL-Histidine monohydrochloride monohydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Histidine HCl Monohydrate) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH using potentiometric or visual endpoint detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Determines trace heavy metals by measuring absorption of characteristic atomic spectral lines after atomization. |
| Chloride Impurity | Argentometric Titration | Quantifies chloride ions by titration with standardized silver nitrate solution using potassium chromate indicator. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled incineration at 500-600 C followed by weighing. |
| Related Substances | HPLC with UV Detection | Separates and quantifies impurities using reversed-phase chromatography and UV absorbance at 210 nm. |
| Optical Rotation | Polarimetry | Measures specific rotation of solution using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| pH of Solution | Potentiometric pH Measurement | Determines hydrogen ion activity in aqueous solution using calibrated glass electrode and reference electrode. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile residue after ignition at 700-800 C, representing inorganic ash content. |
| Iron (Fe) Content | ICP-OES | Detects iron by measuring intensity of element-specific emission lines after plasma atomization and excitation. |
| Loss on Drying | Thermogravimetric Analysis | Measures mass loss upon heating under controlled conditions to determine volatile components including residual solvents. |
| Microbial Limits | Membrane Filtration and Plate Count | Assesses total aerobic microbial count and absence of specified pathogens using selective culture media and incubation. |
