Manufacturing Quality Control of D-Alanine Methyl Ester Hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-Alanine Methyl Ester Hydrochloride) | Acid-Base Titration with NaOH | Quantifies active compound by neutralizing HCl salt with standardized NaOH using potentiometric or visual endpoint detection. |
| Optical Purity (Enantiomeric Excess) | Chiral HPLC | Separates D- and L-enantiomers on a chiral stationary phase; quantifies D-isomer purity via peak area ratio. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric reaction of iodine with water in anhydrous methanol-based medium. |
| Residual Solvents (Methanol, Ethyl Acetate) | Gas Chromatography (GC-FID) | Separates and quantifies volatile solvents using capillary column and flame ionization detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace metal impurities after acid digestion by measuring elemental mass-to-charge ratios with high sensitivity. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions by titration with silver nitrate using silver indicator electrode. |
| pH (1% aqueous solution) | pH Meter Measurement | Measures hydrogen ion activity in aqueous solution using calibrated glass electrode. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting and against standard references. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Related Substances (Impurity Profile) | Reverse-Phase HPLC-UV | Separates and detects structurally related impurities (e.g., D-alanine, methyl ester hydrolysis products) using C18 column and UV detection. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and weighing of residual residue. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration. |
