Manufacturing Quality Control of ethyl DL-methionate hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Methionine Ethyl Ester Hydrochloride) | Acid-Base Titration with NaOH | Quantifies active compound by neutralizing HCl salt with standardized NaOH and back-titrating excess base. |
| Water Content | Karl Fischer Titration | Measures water via iodometric reaction where water consumes iodine in a stoichiometric, electrochemically monitored process. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metals (e.g., Pb, Cd, As) by measuring absorption of element-specific light after atomization in flame or graphite furnace. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using a silver indicator electrode to detect endpoint potential shift. |
| Related Substances | Reverse-Phase HPLC with UV Detection | Separates and quantifies impurities and degradation products using C18 column and UV absorbance at 210 nm. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral compound in solution using plane-polarized light to confirm enantiomeric composition. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determines acidity/basicity of solution using calibrated glass electrode and reference electrode system. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after drying and weighing. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measures volatile loss (e.g., solvent, moisture) by weight difference before and after controlled heating under specified conditions. |
| Microbial Limits | Membrane Filtration and Colony Counting | Detects aerobic microorganisms by filtration, membrane transfer to culture media, incubation, and colony enumeration. |
| Appearance and Color | Visual Inspection and Hazen (APHA) Scale | Evaluates physical state and color intensity by comparison against platinum-cobalt standard solutions under controlled lighting. |
