Manufacturing Quality Control of Trans-(1R,2R)N,N'-Dimethyl-cyclohexane-1,2-diamine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration standard using retention time matching and response factor correction. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Separates (1R,2R) and (1S,2S) enantiomers on a chiral stationary phase; ee calculated from peak area ratio. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and cooling to constant weight. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection of trace metals by measuring atomic emission intensities at characteristic wavelengths after acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions based on ion exchange retention and conductivity detection. |
| Residual Solvents (e.g., methanol, toluene) | Headspace Gas Chromatography (HS-GC) | Analyzes volatile solvents in sample headspace using GC-FID or GC-MS with calibrated standards. |
| Acid Value | Acid-Base Titration (NaOH, phenolphthalein) | Measures free carboxylic acid or acidic impurities by titration with standardized sodium hydroxide solution. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color intensity against platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Specific Optical Rotation | [alpha]D Measurement | Determines rotation angle of plane-polarized light at 589 nm to confirm chiral integrity and concentration. |
| pH (10% w/w aqueous solution) | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode in aqueous dilution. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of particulates or phase separation in a clear container under controlled lighting. |
