Manufacturing Quality Control of MALONIC-D2 ACID-D2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210 nm based on peak area comparison to reference standard. |
| Deuterium Isotopic Purity | 1H NMR | Determines D-incorporation at methylene positions by integration ratio of residual CH2 vs CD2 proton signals in deuterated solvent. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide-pyridine-methanol reagent system. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic impurities (e.g., methanol, acetone) using capillary GC with flame ionization detection. |
| Heavy Metals | ICP-MS | Detects trace metal contaminants (e.g., Pb, Cd, Hg) by plasma ionization followed by mass spectrometric quantification. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride anions using suppressed conductivity detection after anion-exchange separation. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate anions using suppressed conductivity detection after anion-exchange separation. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., mono-deuterated analogs, decarboxylation products) using gradient HPLC-UV. |
| pH (1% aqueous solution) | Potentiometric Titration | Measures hydrogen ion activity using calibrated pH electrode in standardized aqueous solution. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid phase transition using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting conditions. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C followed by weighing. |
