Manufacturing Quality Control of D-LYSINE METHYL ESTER DIHYDROCHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-Lysine Methyl Ester Dihydrochloride Content) | Acid-Base Titration with NaOH (non-aqueous or aqueous, using potentiometric endpoint detection) | Quantifies the main component by neutralizing hydrochloric acid moieties with standardized sodium hydroxide; endpoint determined potentiometrically for precision. |
| Enantiomeric Purity (D/L Ratio) | Chiral HPLC with UV detection | Separates D- and L-enantiomers on a chiral stationary phase; quantification based on peak area ratio using enantiomer-specific calibration. |
| Water Content | Karl Fischer Coulometric Titration | Measures trace water via electrochemical generation of iodine in titration cell; stoichiometric reaction with water ensures high accuracy and sensitivity. |
| Residual Solvents (e.g., Methanol, Ethyl Acetate) | Headspace Gas Chromatography (HS-GC) with FID | Volatiles are equilibrated in headspace vial, injected into GC column, separated, and quantified by flame ionization detection against calibrated standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS (Inductively Coupled Plasma Mass Spectrometry) | Digests sample in acid matrix, atomizes/ionizes elements in plasma, and detects isotopic masses with ultra-trace sensitivity and multi-element capability. |
| Chloride Ion Impurity | Potentiometric Titration with Silver Nitrate | Measures chloride by precipitation with AgNO₃; endpoint detected via silver-ion-selective electrode response change. |
| Related Substances (Impurity Profile) | Reverse-Phase HPLC with UV detection | Separates and quantifies structurally related impurities (e.g., D-lysine, methyl ester hydrolysis products) using C18 column and gradient elution. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Determines acidity/basicity of aqueous solution using calibrated glass electrode and pH meter under controlled temperature. |
| Appearance and Color | Visual Inspection & APHA Color Scale | Assesses physical state (crystalline powder), color (vs. platinum-cobalt standard), and clarity in solution per USP <1092>. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Measures non-volatile inorganic residue after controlled ignition at 700–800 °C; weight difference reflects inorganic impurity content. |
| Microbial Contamination | Membrane Filtration followed by TSA/SDA Plating | Detects aerobic bacteria, yeasts, and molds via filtration, culture on tryptic soy agar/sabouraud dextrose agar, and colony enumeration per Ph. Eur. 2.6.12. |
