Industrial Applications of Calcium 2-oxoglutarate
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals & Nutraceuticals | Parenteral nutrition formulations; serves as a glutamine precursor to support protein synthesis, wound healing, and nitrogen balance | Combined with amino acids, glucose, and other excipients, then sterile-filled into injectables or dual-chamber bags |
| Food & Feed | Nutritional fortificant supplying calcium and alpha-ketoglutaric acid to support growth metabolism | Directly added or blended with other nutrients prior to granulation |
| Food | Acidity regulator (acidulant) for flavor enhancement | Directly incorporated and mixed during food processing |
| Chemical & Biomanufacturing | Nitrogen source supplement in industrial fermentation processes to support microbial growth, metabolism, and enzyme activity modulation | Added during fermentation medium preparation |
| Feed | Animal feed additive to mitigate stress responses, enhance immune function, and improve growth performance | Homogeneously blended with feed ingredients prior to pelleting or premix formulation |
Manufacturing Quality Control of Calcium 2-oxoglutarate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (CaC5H4O5) | Acid-Base Titration | Direct titration with standardized NaOH after dissolution and acidification; quantifies alpha-ketoglutaric acid moiety via neutralization of carboxylic groups. |
| Calcium Content | EDTA Complexometric Titration | Calcium ions form a stable 1:1 complex with EDTA at pH 10; endpoint detected by Eriochrome Black T or Calcon indicator. |
| Loss on Drying | Gravimetric Method (Oven Drying) | Mass loss measured after drying at 105 C for 2 h; reflects volatile impurities and residual solvents. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and pyridine/methanol reagents to quantify water stoichiometrically. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using lead as the reference element under flame or graphite furnace conditions. |
| Residue on Ignition | Gravimetric Method (Sulfated Ash) | Mass of inorganic residue after ignition at 600 C; indicates non-volatile inorganic impurities. |
| pH (1% aqueous solution) | Potentiometric Measurement | Hydrogen ion activity measured using calibrated glass electrode in a defined aqueous suspension. |
| Chloride | Argentometric Titration (Mohr Method) | Titration with standardized AgNO3; chloride forms precipitate with Ag+, endpoint indicated by red Ag2CrO4 formation. |
| Sulfate | Barium Sulfate Gravimetric Method | Precipitation as BaSO4 in acidic medium followed by filtration, drying, and weighing. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Separation on reversed-phase C18 column with UV detection at 210 nm; identifies and quantifies structurally related impurities. |
| Microbial Limits | Membrane Filtration and Plate Count | Sample filtration followed by incubation on tryptic soy agar (TSA) and sabouraud dextrose agar (SDA); enumerates aerobic bacteria and fungi. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to determine volume-based size distribution in micrometers. |
