Manufacturing Quality Control of sodium 4-oxovalerate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Sodium Levulinate) | Acid-Base Titration | Direct titration with standardized HCl after acid hydrolysis to liberate levulinic acid, using phenolphthalein or potentiometric endpoint detection. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in a methanol-based reagent. |
| pH (1% aqueous solution) | pH Meter Measurement | Electrochemical measurement using calibrated glass electrode in a 1% w/v aqueous solution at 25 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using air-acetylene flame AAS at characteristic wavelengths. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 500-600 C followed by weighing of residual inorganic ash after sulfuric acid treatment. |
| Chloride | Argentometric Titration (Mohr method) | Titration with standardized AgNO3 solution using potassium chromate indicator; endpoint signaled by brick-red Ag2CrO4 precipitate. |
| Sulfate | Barium Sulfate Gravimetric Method | Precipitation as BaSO4 after acidification and addition of BaCl2, followed by ignition and weighing of dried precipitate. |
| Iron (Fe) | UV-Vis Spectrophotometry | Formation of orange-red Fe(II)-1,10-phenanthroline complex measured at ~510 nm after reduction with hydroxylamine. |
| Loss on Drying | Thermogravimetric Method | Weight loss measured after drying at 105 C for 2 hours under standard atmospheric pressure. |
| Residue on Ignition | Gravimetric Analysis | Weight of non-volatile residue remaining after ignition at 700 C for 30 minutes. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light using sodium D-line (589 nm) in a 10% w/v solution at 20 C. |
| Microbial Contamination | Membrane Filtration Method | Filtration of solution through sterile membrane, followed by incubation on appropriate agar media and colony enumeration. |
