Manufacturing Quality Control of 3-Hydroxybutanoic acid calcium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (C8H14CaO6) | Acid-Base Titration with NaOH | Quantifies 3-hydroxybutyric acid content after acid hydrolysis and back-titration. |
| Calcium Content | Complexometric Titration with EDTA | Measures Ca2+ by formation of stable EDTA-Ca complex at controlled pH. |
| Loss on Drying | Gravimetric Analysis (Thermogravimetry) | Determines volatile matter by weight loss after drying at specified temperature and time. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Measures inorganic impurities remaining after high-temperature ignition. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metal elements based on element-specific atomic emission spectra. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects Cl- via silver chloride precipitation and endpoint detection using Ag electrode. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates SO4(2-) as BaSO4 and determines mass after filtration and drying. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection. |
| Water Content | Karl Fischer Coulometric Titration | Measures water via electrochemical iodine generation and stoichiometric reaction with water. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in standardized suspension. |
| Microbial Limits | Membrane Filtration and Colony Counting | Quantifies aerobic microorganisms by filtration, membrane transfer, and incubation on nutrient agar. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution based on angular dependence of scattered laser light intensity. |
