Manufacturing Quality Control of D-(+)-Phenyllactic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 210 nm, based on peak area comparison against a certified reference standard. |
| Optical Rotation | [alpha]D | Measurement of specific rotation using a polarimeter at 20 degrees C with sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 degrees C and weighing residual inorganic ash to assess inorganic impurities. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally related impurities (e.g., D-phenyllactic acid isomers, dehydration products) using diode-array detection. |
| pH of Aqueous Solution | Potentiometric Titration | Measurement of pH in a 1% w/v aqueous solution using calibrated pH electrode to assess acid strength and potential degradation. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Loss on Drying | Thermogravimetric Analysis | Weight loss measured after drying at 105 degrees C for 2 hours to assess volatile solvents or moisture. |
| Sulfated Ash | Gravimetric Analysis | Residue weight after incineration with sulfuric acid treatment to detect metallic sulfate-forming impurities. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and absence testing for specified pathogens per pharmacopeial microbial limits. |
