Manufacturing Quality Control of L-tert-Leucine hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (L-tert-Leucine Hydrochloride) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH using bromocresol green indicator. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to confirm chiral purity and identity. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric reaction with iodine and Karl Fischer reagent. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and weighing. |
| Chloride Impurity | Potentiometric Titration | Quantifies chloride ions by titration with silver nitrate using silver electrode detection. |
| Heavy Metals | ICP-OES | Simultaneously detects multiple heavy metal elements (e.g., Pb, Cd, Hg) based on atomic emission spectra. |
| Related Substances | HPLC-UV | Separates and quantifies structurally similar impurities using reversed-phase chromatography and UV detection. |
| Enantiomeric Purity | Chiral HPLC | Resolves L- and D-enantiomers on a chiral stationary phase and quantifies D-isomer content. |
| pH (1% aqueous solution) | pH Meter Measurement | Determines acidity/basicity of aqueous solution using calibrated pH electrode. |
| Loss on Drying | Thermogravimetric Analysis | Measures weight loss upon heating under controlled temperature and time to assess volatile content. |
| Sulfated Ash | Gravimetric Analysis | Determines non-volatile inorganic residue after sulfuric acid treatment and high-temperature ignition. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration. |
