Manufacturing Quality Control of H-D-ALA-OET HCL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-Alanine Ethyl Ester Hydrochloride) | Acid-Base Titration with NaOH | Quantifies active compound by neutralizing HCl salt with standardized NaOH using phenolphthalein or potentiometric endpoint detection. |
| Optical Rotation | [alpha]D Measurement | Determines enantiomeric purity by measuring rotation of plane-polarized light at 20 C and 589 nm using a calibrated polarimeter. |
| Water Content | Karl Fischer Titration | Measures trace water via stoichiometric iodine reaction with sulfur dioxide and methanol in pyridine-free reagent system. |
| Residual Solvents (Ethanol, Ethyl Acetate) | Gas Chromatography (GC) with FID | Separates and quantifies volatile solvents using capillary column and flame ionization detection against external standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Quantifies trace metals after acid digestion by measuring elemental mass-to-charge ratios with high sensitivity and multi-element capability. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using silver indicator electrode and reference electrode. |
| Related Substances (Impurity Profile) | HPLC with UV Detection | Separates and quantifies structurally related impurities (e.g., D-alanine, ethyl ester hydrolysis products) on reversed-phase C18 column at 210 nm. |
| pH (1% w/v aqueous solution) | pH Meter Measurement | Determines acidity/basicity of aqueous solution using calibrated glass electrode pH meter at 25 C. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid sample against standard white background under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated digital melting point instrument. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled ashing at 700-800 C and subsequent weighing. |
| Microbial Contamination | Membrane Filtration and Plate Count | Quantifies aerobic microorganisms by filtration, membrane transfer to soybean-casein digest agar, and colony enumeration after incubation. |
