Manufacturing Quality Control of METHYL 2-AMINO-3-MERCAPTOPROPANOATE HYDROCHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-Cysteine Methyl Ester Hydrochloride) | Acid-Base Titration | Quantifies active compound by titration with standardized NaOH using bromocresol green indicator; endpoint corresponds to neutralization of HCl salt and carboxylic acid group. |
| Chiral Purity | Chiral HPLC | Separates D- and L-enantiomers on a chiral stationary phase; enantiomeric excess calculated from peak area ratio. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residual Solvents (Methanol, Ethyl Acetate) | Gas Chromatography (GC-FID) | Quantifies volatile organic solvents using flame ionization detection after headspace or direct injection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace metal impurities by ionizing sample in plasma and measuring elemental mass-to-charge ratios with high sensitivity. |
| Chloride Content | Potentiometric Titration | Determines chloride ions by titration with AgNO3 using silver indicator electrode; endpoint detected by potential change. |
| pH (1% w/v aqueous solution) | pH Meter Measurement | Measures hydrogen ion activity in aqueous solution using calibrated glass electrode system. |
| Related Substances | Reverse-Phase HPLC | Identifies and quantifies structurally related impurities (e.g., D-cysteine, methyl ester hydrolysis products) using C18 column and UV detection. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as BaSO4 under controlled conditions; quantified by drying and weighing the precipitate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against standard reference under controlled lighting. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measures mass loss upon heating under nitrogen or air; reflects volatile content including residual solvents and moisture. |
| Microbial Limits | Membrane Filtration | Determines total aerobic microbial count and absence of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial guidelines. |
