Manufacturing Quality Control of DIETHYLENETRIAMINEPENTAACETIC DIANHYDRIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies DTPA-dianhydride by hydrolysis to DTPA followed by titration of carboxylic acid groups with standardized sodium hydroxide. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in a pyridine-methanol solvent system. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration and weighing of residual non-volatile matter. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring absorbance of ground-state atoms at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after drying and weighing. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode and reference electrode. |
| Melting Point | Capillary Melting Point Determination | Observes temperature range over which solid transitions to liquid using capillary tube and calibrated apparatus. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents or low-MW organics using capillary column and flame ionization detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Evaluates yellowness intensity against platinum-cobalt standard scale using spectrophotometer at 430 nm. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension by analyzing angular variation of scattered laser light. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring rotation angle of plane-polarized light passing through a solution at specified concentration and wavelength. |
