Manufacturing Quality Control of 1,4-Diiodobutane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Volatile impurities are vaporized in headspace vial and quantified by GC-FID using calibration curves. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acidity (as HI) | Acid-Base Titration with NaOH | Titration of acidic impurities (e.g., hydroiodic acid) using standardized sodium hydroxide solution and potentiometric or visual endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection via ionization in plasma and mass spectrometric quantification using isotope dilution or external calibration. |
| Iodide Ion (I-) | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by quantitative detection based on electrical conductivity. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color to APHA platinum-cobalt standards or absorbance measurement at specified wavelength. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Digital Refractometer | Determination of refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Non-Volatile Residue | Gravimetric Analysis (Weight Loss on Drying) | Evaporation of volatile components at controlled temperature followed by weighing of residual solids. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Appearance (Clarity) | Visual Inspection in Nessler Tube | Subjective assessment of clarity and presence of suspended particles or phase separation against white background under controlled lighting. |
