Manufacturing Quality Control of 376-68-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active anhydride content by hydrolysis followed by titration with standardized NaOH solution. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by high-temperature ashing and weighing of residual mass. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Fe, Ni) after acid digestion using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under controlled conditions and determines mass by gravimetric analysis. |
| Color | Visual Comparison or Spectrophotometry | Evaluates color intensity against platinum-cobalt standard solutions or at 430 nm absorbance. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents and volatile organics using flame ionization detection. |
| Acid Number | Acid-Base Titration | Determines total acidic functionality (including hydrolyzed anhydride) by titration with KOH in ethanol. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension using angular scattering pattern analysis. |
| Bulk Density | Gravimetric Volumetric Method | Calculates mass per unit volume of freely settled powder in a standardized cylinder. |
