Manufacturing Quality Control of 4-Propylbiphenyl
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 4-n-propylbiphenyl peak area relative to calibrated standard curve. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents by equilibrium partitioning into headspace followed by GC separation. |
| Moisture Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies elemental metal contaminants (e.g., Pb, Cd, Hg, As) by atomic emission intensity at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions by titration with silver nitrate using a silver indicator electrode; endpoint detected by potential inflection. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or phase separation under controlled lighting and conditions. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Determines mass per unit volume after mechanical tapping to assess powder flow and packing characteristics. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles by analyzing angular variation in laser light scattering intensity. |
| Sulfated Ash | Gravimetric Analysis | Quantifies non-volatile inorganic residue after high-temperature combustion and sulfuric acid treatment, expressed as weight percent. |
