Manufacturing Quality Control of Dibutyl fumarate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies DBF concentration by separation and detection relative to a calibration curve using a suitable column and detector. |
| Acid Value | Acid-Base Titration | Measures free acid content by titration with standardized KOH solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric reaction between water and iodine in a pyridine-methanol solvent system. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standards or measuring absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Determines light bending angle in sample using Abbe refractometer calibrated with distilled water. |
| Residue on Evaporation | Gravimetric Analysis | Quantifies non-volatile impurities by evaporating known mass of sample and weighing residual solids. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Detects total heavy metals after wet digestion by measuring atomic absorption of lead-specific wavelength. |
| Iron Content | UV-Vis Spectrophotometry | Measures Fe2+ complex with 1,10-phenanthroline at 510 nm after reduction and chelation. |
| Chloride Content | Potentiometric Titration | Quantifies chloride ions by titration with silver nitrate using silver indicator electrode. |
| Non-Volatile Matter | Gravimetric Analysis | Determines insoluble residue after filtration and drying of diluted sample. |
| Distillation Range | Vacuum Distillation | Measures temperature interval over which 90% of sample distills under controlled vacuum conditions. |
