Manufacturing Quality Control of sodium;3,4-dihydroxy-4-oxobutanoate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Malic Acid Sodium Salt) | Acid-Base Titration | Quantifies active ingredient by titration with standardized HCl using phenolphthalein or potentiometric endpoint detection. |
| Loss on Drying | Gravimetric Method | Measures weight loss after drying at 105 C for 2 hours to determine volatile content including moisture. |
| pH of Aqueous Solution | Potentiometric Method | Determines hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Sulfate Impurity | Turbidimetric Method | Measures sulfate as barium sulfate precipitate formed in acidic medium, detected via light scattering. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of ground-state atoms at characteristic wavelength. |
| Iron (Fe) | ICP-OES | Determines iron concentration by measuring intensity of emitted radiation from excited Fe atoms in plasma. |
| Residue on Ignition | Gravimetric Method | Measures non-volatile inorganic residue remaining after ignition at 600 C for 30 minutes. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral DL-malic acid sodium salt in solution. |
| Related Substances | HPLC-UV | Separates and quantifies impurities using reversed-phase chromatography with UV detection at 210 nm. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine generated electrochemically in methanol-based reagent. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens using selective culture media and incubation. |
