Manufacturing Quality Control of dipotassium;propanedioate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | Acid-base titration | Titration with standardized HCl solution using bromocresol green indicator; endpoint corresponds to complete protonation of malonate anion. |
| Water content | Karl Fischer titration | Electrochemical titration using iodine, sulfur dioxide, and pyridine in methanol; quantifies water based on stoichiometric reaction. |
| Chloride impurity | Ion chromatography (IC) | Separation of chloride ions on an anion-exchange column followed by conductivity detection. |
| Sulfate impurity | Gravimetric analysis | Precipitation as BaSO4 in acidic medium and weighing of dried precipitate. |
| Heavy metals (as Pb) | Atomic absorption spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using lead as the reference element and air-acetylene flame. |
| Iron (Fe) | Inductively coupled plasma optical emission spectrometry (ICP-OES) | Multi-element detection after acid digestion; measures Fe atomic emission at characteristic wavelength. |
| Loss on drying (LOD) | Thermogravimetric analysis (TGA) | Mass loss measured upon heating to 105 C for 2 hours under ambient atmosphere. |
| pH of aqueous solution | Potentiometric pH measurement | Measurement using calibrated glass electrode in 1% w/v aqueous solution at 25 C. |
| Residue on ignition | Gravimetric analysis | Weighing residue remaining after incineration at 700 C for 30 minutes. |
| Organic impurities | High-performance liquid chromatography (HPLC) | Separation on reversed-phase C18 column with UV detection at 210 nm; uses external standards for quantification. |
| Particle size distribution | Laser diffraction | Analysis of light scattering pattern from dispersed sample in liquid medium to determine volume-based particle size distribution. |
| Bulk density | Graduated cylinder method | Mass of material freely poured into a calibrated cylinder divided by its settled volume. |
