| Organic Synthesis | Arylpropionyl structural unit for constructing complex compounds | Catalytic reactions, functional group transformations |
Manufacturing Quality Control of 4-PROPIONYLBIPHENYL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-DAD or HPLC-MS | Separation and identification of impurities (e.g., unreacted 4-bromobiphenyl, propionic acid derivatives) via retention time matching and spectral/fragmentation analysis. |
| Residual Solvents (e.g., toluene, THF, methanol) | GC-FID | Headspace or direct injection GC with flame ionization detection; quantification using external calibration curves per ICH Q3C guidelines. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion, leveraging high sensitivity and isotopic resolution for trace metal impurities per ICH Q3D. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine is generated in situ; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change under controlled heating rate; used for identity and purity assessment. |
| Appearance & Color | Visual Inspection / APHA Color Scale | Subjective visual evaluation against water or platinum-cobalt standards to detect discoloration or particulate contamination. |
| Residue on Ignition | Gravimetric Analysis | Mass difference after high-temperature ashing (700–800 °C) to determine inorganic residue content per USP <281>. |
