| Industry | Application | Process |
|---|---|---|
| Chemical | Organic synthesis intermediate | Used as a precursor in the synthesis of citric acid, isocitric acid, and other tricarboxylic acid (TCA) cycle-related compounds, applied in catalytic or enzymatic transformation reactions |
| Pharmaceutical | Pharmaceutical intermediate | Applied in the synthesis of bioactive molecules—such as antiviral agents or metabolic modulators—via esterification, acylation, or dehydration reactions to introduce carboxyl functionality |
| Food | Acidulant and indirect preservative | Employed as an intermediate in citric acid metabolism during food processing; biotransformed to regulate pH and inhibit microbial growth |
| Biotechnology | Metabolic research reagent | Used in studies of cellular metabolic pathways—including the TCA cycle—as a reference standard or tracer in enzyme kinetic analysis |
| Agriculture | Plant growth regulator (research stage) | Applied as a modulator of organic acid metabolism in plants to investigate its effects on root development and nutrient uptake |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities by retention time and UV spectral matching; detection and quantification using diode array detector. |
| Loss on Drying | Gravimetric (Oven Drying) | Mass loss measured after drying sample at 105 C for 2 hours under atmospheric pressure. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Residue mass determined after charring and incineration at 700-800 C, following sulfuric acid treatment. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantification of total heavy metals by atomic absorption spectroscopy after acid digestion and matrix-matched calibration. |
| Chloride | Ion Chromatography (IC) | Separation and quantification of chloride ions using an anion-exchange column and suppressed conductivity detection. |
| Sulfate | Turbidimetry | Measurement of turbidity generated by barium sulfate precipitate formed upon reaction with barium chloride in acidic medium. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric determination of water based on iodine consumption in a pyridine/methanol solvent system. |
| pH (1% aqueous solution) | Potentiometric (pH Meter) | Measurement of hydrogen ion activity using calibrated glass electrode in a 10 mg/mL aqueous solution at 25 C. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid-to-liquid phase transition occurs, using capillary tube and controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, corrected for concentration and path length. |
| Microbial Limits | Membrane Filtration + Culture | Enumeration of aerobic microorganisms and detection of specified pathogens by filtration, membrane transfer to selective media, and incubation. |
