Manufacturing Quality Control of Oxobutanedioic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Oxaloacetic Acid Content Determination | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column and a UV detector (typically at 210–260 nm wavelength), with a mobile phase gradient elution of phosphate buffer and organic solvent (e.g., methanol or acetonitrile) to separate and quantify oxaloacetic acid from other organic acids. Offers high sensitivity and resolution, suitable for purity and content analysis. |
| Enzymatic Method (Spectrophotometry) | Leverages a specific enzymatic reaction involving oxaloacetic acid, such as its conversion to malate by malate dehydrogenase (MDH), simultaneously reducing NAD⁺ to NADH. The concentration of oxaloacetic acid is indirectly quantified by measuring the absorbance change of NADH at 340 nm. Simple to operate, highly specific, and suitable for detection in biological samples. | |
| UV-Visible Spectrophotometry | Oxaloacetic acid exhibits a characteristic absorption peak around 210 nm, allowing direct concentration measurement via UV-Vis spectroscopy. However, it is prone to interference from coexisting impurities and is typically used for rough estimation or preliminary screening. | |
| Mass Spectrometry (LC-MS/MS) | Combines liquid chromatography with tandem mass spectrometry to perform qualitative and quantitative analysis based on the molecular ion peak ([M-H]⁻ m/z ≈ 131) and characteristic fragment ions. Offers high sensitivity and selectivity, ideal for trace-level detection of oxaloacetic acid in complex matrices and structural confirmation. | |
| Capillary Electrophoresis (CE) | Separates oxaloacetic acid based on differences in electrophoretic mobility under alkaline buffer conditions, followed by detection using UV or conductivity detectors. Requires minimal sample volume and provides high separation efficiency, making it suitable for analyzing ionic compounds. |
