Manufacturing Quality Control of 2,2':5',2''-TERTHIOPHENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies alpha-terthiophene by separation on a reversed-phase column and UV absorbance detection at ~320 nm. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally similar impurities (e.g., bithiophene, quaterthiophene) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., toluene, THF) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based redox reaction. |
| Heavy Metals | ICP-OES | Measures total elemental impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion by plasma optical emission spectroscopy. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions using anion-exchange column and conductivity detection after sample dissolution. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion with sulfuric acid treatment and high-temperature ignition. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against standard reference. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of a powder sample in a graduated cylinder. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles by analyzing angular scattering pattern of laser light. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated electrode. |
