Manufacturing Quality Control of L-(-)-3-Phenyllactic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Optical Rotation | [alpha]D | Measurement of specific rotation using a digital polarimeter at 20 degC with sodium D-line (589 nm) light source. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent; water reacts stoichiometrically to determine trace moisture. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-750 degC to constant weight and measuring inorganic ash content by mass difference. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion, based on atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride anions using anion-exchange column and eluent gradient. |
| Related Substances | HPLC-DAD | Detection and relative quantification of structurally similar impurities using diode-array detection across 200-400 nm. |
| pH (1% aqueous solution) | Potentiometric Titration | Measurement of hydrogen ion activity using calibrated pH electrode in a 10 mg/mL aqueous solution. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using controlled heating and visual observation. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Mass loss measured under controlled nitrogen flow while heating from 25 to 105 degC for 2 hours. |
| Sulfated Ash | Gravimetric Analysis | Sample treated with sulfuric acid, ignited at 600 degC, and residual sulfate ash determined by weight. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic mesophilic bacteria and molds/yeasts via filtration, membrane transfer, and incubation on appropriate agar media. |
