Manufacturing Quality Control of 3,6,9-trioxaundecamethylenediamine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 200–220 nm, comparing peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration based on the stoichiometric reaction of iodine with water in a methanol-based solvent system. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic impurities (e.g., THF, ethanol) using capillary GC with flame ionization detection. |
| Heavy Metals | ICP-MS | Multi-element detection of trace metals (Pb, Cd, Hg, As, Ni) after acid digestion, utilizing plasma ionization and mass spectrometric detection. |
| Acid Value | Acid-Base Potentiometric Titration | Titration with standardized KOH solution to neutralize free carboxylic acids or acidic impurities; endpoint determined by pH inflection. |
| Amine Content | Non-aqueous Acidimetric Titration | Titration with standardized perchloric acid in glacial acetic acid using crystal violet indicator to quantify primary amine groups. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample solution color intensity against platinum-cobalt standards, measured as absorbance at 430 nm. |
| Residue on Ignition | Gravimetric Analysis | Heating at 700–750 °C to volatilize organic matter, followed by weighing of inorganic residue. |
| Related Substances | HPLC-UV (with Gradient Elution) | Separation and identification of structurally related impurities (e.g., mono/di-substituted analogs, hydrolysis products) using gradient RP-HPLC and UV spectral comparison. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Direct measurement of hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution at specified wavelength (589 nm) and temperature (20 °C). |
