Manufacturing Quality Control of DL-Threonine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Threonine Content) | Acid-Base Titration with NaOH | Quantifies threonine by neutralizing its carboxylic acid group using standardized sodium hydroxide solution. |
| Specific Optical Rotation | Polarimetry | Measures the rotation of plane-polarized light caused by chiral DL-threonine in solution. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Determines volatile content by measuring mass loss after drying at specified temperature and time. |
| Residue on Ignition | Gravimetric (Ash Residue) | Quantifies inorganic impurities by measuring residue mass after high-temperature ignition. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration using a silver indicator electrode. |
| Sulfate Content | Turbidimetry with BaCl2 | Measures sulfate as barium sulfate precipitate formed in acidic medium, quantified by light scattering. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample and measuring absorption of characteristic wavelength light. |
| Iron (Fe) Content | UV-Vis Spectrophotometry with 1,10-Phenanthroline | Forms colored complex with Fe2+; absorbance measured at ~510 nm for quantification. |
| pH of Aqueous Solution | Potentiometric (pH Meter) | Measures hydrogen ion activity in 1% w/v aqueous solution using calibrated glass electrode. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally similar impurities using reversed-phase C18 column and UV detection. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtering sample, culturing on agar, and counting colony-forming units. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles by analyzing angular variation in laser light scattering. |
