Manufacturing Quality Control of (S)-(+)-2-Phenylpropionic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV absorbance at 210-230 nm. |
| Related Substances | HPLC with UV detection | Separation and quantification of impurities (e.g., unreacted precursors, isomers, degradation products) relative to main peak using gradient elution and UV detection. |
| Residual Solvents | Gas Chromatography (GC) with FID | Identification and quantification of volatile organic solvents (e.g., toluene, ethyl acetate) by retention time matching and calibration curve analysis. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in anhydrous methanol-based reagent. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Residue mass measured after high-temperature incineration followed by sulfuric acid treatment and ignition to constant weight. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric excess. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of particulates or discoloration under controlled lighting against standard specifications. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined water suspension (e.g., 1% w/v) to detect acidic/basic impurities affecting stability. |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile residue remaining after ignition at 700-800 C, indicating inorganic impurities. |
