Manufacturing Quality Control of (+/-)-trans-1,2-Diaminocyclohexane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies trans-1,2-cyclohexanediamine peak area relative to calibrated standard using retention time and response factor. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separates and quantifies impurities (e.g., cis-isomer, monoamine, oligomers) based on retention time and peak area. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine generation in pyridine/methanol solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Amine Value | Acid-Base Titration with HCl | Measures total primary and secondary amine content by back-titration after reaction with excess standardized hydrochloric acid. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 455 nm in a 10-mm cell. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature-controlled measurement. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through the sample at specified wavelength (usually sodium D line) to infer purity and composition. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume under controlled conditions and weighs non-volatile residue to assess inorganic/organic contaminants. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions using conductivity detection (IC) or silver nitrate titration with indicator electrode. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample in flame or graphite furnace and measuring absorption at characteristic wavelengths. |
| Residual Solvents | Gas Chromatography (GC) with Headspace Sampling | Detects and quantifies volatile solvents (e.g., methanol, toluene) using equilibrium headspace gas analysis and FID detection. |
