Manufacturing Quality Control of [2，2’]bithiophenyl-5,5'-dicarbaldehyde
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities by comparing retention times and peak areas against reference standards or threshold limits. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using gas chromatography with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Heavy Metals | ICP-OES | Determines total elemental metal impurities (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on an anion-exchange column. |
| Sulfate Content | Ion Chromatography | Quantifies sulfate ions using suppressed conductivity detection after separation on an anion-exchange column. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized white light and against reference standards. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using angular scattering pattern analysis. |
| Bulk Density | USP <616> Tap Density Method | Measures mass per unit volume of powder after controlled tapping in a graduated cylinder. |
