Manufacturing Quality Control of L-Methionine methyl ester hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (L-Methionine Methyl Ester Hydrochloride) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH using phenolphthalein indicator; endpoint corresponds to neutralization of HCl salt and ester hydrolysis. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water, iodine, sulfur dioxide, and base in anhydrous methanol medium. |
| Optical Rotation | Polarimetry | Determines enantiomeric purity by measuring the angle of rotation of plane-polarized light in a solution at specified concentration and wavelength. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal impurities (e.g., Pb, Cd, As) after acid digestion by measuring absorption of element-specific wavelengths. |
| Chloride Content | Argentometric Titration (Mohr method) | Determines chloride ion concentration by titration with standardized AgNO3 using K2CrO4 as indicator; forms red Ag2CrO4 at endpoint. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by ignition at 700-800 C and weighing residual ash after cooling in desiccator. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally related impurities (e.g., L-methionine, methyl ester hydrolysis products) using reversed-phase C18 column and UV detection. |
| pH (1% aqueous solution) | pH Potentiometry | Measures hydrogen ion activity using calibrated pH electrode in a defined aqueous solution at 25 C. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Determines volatile content by weight loss after drying at 105 C for 2 hours under controlled atmospheric conditions. |
| Specific Optical Rotation | Polarimetry | Same principle as optical rotation but reported per unit path length and concentration (deg * mL / g * dm) for standardized comparison. |
| Sulfate Content | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4 in acidic medium; dried and weighed to calculate sulfate mass fraction. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects aerobic microorganisms and absence of specified pathogens (e.g., E. coli, Salmonella) using selective media and incubation. |
