Manufacturing Quality Control of 1,3-Diaminocyclohexane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies 1,3-cyclohexanediamine peak area relative to a calibration curve using an internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Compares sample color to platinum-cobalt standards; spectrophotometric method measures absorbance at 455 nm. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after high-temperature ashing and cooling in desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring absorbance of atomic vapor at element-specific wavelength. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via precipitation titration with silver nitrate using silver electrode for endpoint detection. |
| Specific Gravity | Digital Density Meter | Determines density ratio relative to water at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light passing through sample at 20 degrees C using calibrated prism-based instrument. |
| Optical Rotation | Polarimetry | Quantifies chiral purity by measuring angle of rotation of plane-polarized light in a defined cell path length and concentration. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Identifies and quantifies volatile organic solvents by gas-phase analysis after thermal equilibration in sealed vial. |
| Non-Volatile Residue | Evaporation and Gravimetry | Measures weight of residue after controlled evaporation of sample under nitrogen and drying at 105 degrees C. |
