Manufacturing Quality Control of 3,4'-DI-ISO-PROPYLBIPHENYL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area relative to calibrated standard. |
| 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. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines water via electrochemical generation of iodine reacting stoichiometrically with water in anhydrous medium. |
| Heavy Metals | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Quantifies metal impurities by atomic emission intensity after high-temperature plasma atomization. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using ion-exchange column and conductivity detection. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Measures acidic impurities by titration with standardized sodium hydroxide to phenolphthalein endpoint. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid under controlled heating. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or phase separation against established reference. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after high-temperature ashing and cooling to constant weight. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral impurities or enantiomeric excess. |
| Bulk Density | Tap Density Tester (ASTM D1895) | Determines mass per unit volume of freely settled and tapped powder sample. |
