Manufacturing Quality Control of D-Dimethyl tartrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies D-(-)-dimethyl tartrate peak area relative to a calibrated standard curve. |
| Specific Optical Rotation | [alpha]D measurement using polarimeter | Measures rotation of plane-polarized light induced by chiral molecules in solution at specified temperature and concentration. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Measures non-volatile inorganic residue remaining after combustion at 700-800 C. |
| Heavy Metals | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Atomizes and excites sample in plasma; quantifies metal elements via characteristic emission wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions based on retention time and conductivity response. |
| Sulfated Ash | Gravimetric analysis after sulfuric acid treatment and ignition | Measures inorganic residue after sulfuric acid digestion and subsequent high-temperature ignition. |
| Acid Value | Acid-base titration with NaOH standard solution | Determines free carboxylic acid content by neutralizing with standardized sodium hydroxide. |
| Related Substances | HPLC with UV detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance. |
| Appearance | Visual inspection against standard reference | Assesses physical state, color, and clarity under controlled lighting and viewing conditions. |
| Melting Point | Capillary melting point apparatus | Determines temperature range at which solid transitions to liquid phase using calibrated capillary method. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Quantifies volatile organic solvents by analyzing equilibrium vapor phase above sample at controlled temperature. |
