Manufacturing Quality Control of p-Terphenyl
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Assay | High-Performance Liquid Chromatography (HPLC) | Uses a reverse-phase C18 column with a UV detector (typically at ~254 nm), employing methanol-water or acetonitrile-water as the mobile phase to quantitatively analyze the purity and content of p-terphenyl. Offers high sensitivity and resolution, suitable for detecting trace impurities. |
| Purity and Impurity Analysis | Gas Chromatography (GC) | Applicable to samples with good volatility. Uses a capillary column (e.g., DB-5) with an FID detector; qualitative analysis is performed via retention time, and quantitative analysis is achieved by peak area normalization or external standard method, effectively detecting organic impurities and isomers (ortho-, meta-terphenyl). |
| Structural Confirmation | Ultraviolet-Visible Spectroscopy (UV-Vis) | p-Terphenyl exhibits characteristic absorption peaks in the 250–280 nm range. Comparison with the UV spectrum of a reference standard verifies its conjugated structure and fundamental chemical properties, used for preliminary identification. |
| Crystallinity and Polymorph Analysis | Differential Scanning Calorimetry (DSC) | Measures melting temperature and enthalpy changes to assess crystallinity and detect polymorphic forms. Pure p-terphenyl typically exhibits a sharp, reproducible melting peak at approximately 214–217°C. |
| Water Content | Karl Fischer Titration | Based on the reaction of iodine and sulfur dioxide with water in an anhydrous environment, this method precisely determines trace water content in samples, ensuring the product is sufficiently dry for storage and use. |
| Residual Solvent Detection | Gas Chromatography (GC) | According to ICH guidelines, detects organic solvents potentially residual from manufacturing processes (e.g., benzene, toluene, dichloromethane), using headspace sampling combined with FID or MS detectors to ensure compliance with safety limits. |
| Heavy Metals and Inorganic Impurities | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Detects residual heavy metals such as lead, arsenic, mercury, and cadmium to ensure compliance with pharmaceutical or electronic-grade material impurity control standards. |
| Appearance and Physical Properties | Visual Inspection + Melting Point Determination | Observes sample color and physical state (white to off-white crystalline powder) and measures melting point using a melting point apparatus (standard range: ~214–217°C), serving as a fundamental quality indicator. |
