Manufacturing Quality Control of (R)-(-)-2-Methylpiperazine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against a calibrated standard. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Separates (R)- and (S)-enantiomers on a chiral stationary phase; ee calculated from peak area ratio. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents by equilibrium partitioning into headspace followed by GC analysis. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) by atomic emission after acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography (IC) | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against specified standards under controlled lighting. |
| Specific Rotation | [alpha]D Measurement | Determines optical rotation at 589 nm using sodium D-line to confirm chiral integrity and concentration. |
| pH (10% aqueous solution) | pH Meter Measurement | Measures hydrogen ion activity in aqueous solution to assess acidity/basicity consistent with amine functionality. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic residue after high-temperature ashing and weighing. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities using reversed-phase column and UV absorbance. |
