Manufacturing Quality Control of (1R,2R)-N,N'-Dimethyl-1,2-cyclohexanediamine
| 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. |
| Optical Rotation | [alpha]D Measurement using Polarimetry | Measures the angle of rotation of plane-polarized light, confirming enantiomeric identity and purity. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Separates (1R,2R) and (1S,2S) enantiomers on a chiral column; ee calculated from peak areas. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatiles are extracted into headspace and quantified by GC-FID or GC-MS against solvent standards. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection of metal impurities via atomic emission after acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions based on retention time and conductivity response. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralizes acidic impurities; endpoint detected potentiometrically or with phenolphthalein indicator. |
| Appearance | Visual Inspection in Clear Glass Container | Assesses clarity and color against water-white standard under controlled lighting. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Measures mass per unit volume at specified temperature via resonant frequency shift of a vibrating tube. |
| Refractive Index | Refractometry (Abbe refractometer) | Determines ratio of light velocity in air vs. sample at 20 C using critical angle measurement. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Sample evaporated to dryness at 105 C; residue weighed to determine inorganic/organic non-volatiles. |
