Manufacturing Quality Control of 3-(TRIMETHYLSILYLETHYNYL)THIOPHENE 97
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantifies main component by separation on capillary column and flame ionization detection, using external standard calibration. |
| Residual Solvents | GC-FID with headspace sampling | Identifies and quantifies volatile organic solvents based on partitioning into headspace and chromatographic separation. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Heavy Metals | ICP-OES | Determines total elemental metals (e.g., Pb, Cd, Hg, As) after acid digestion by plasma-induced atomic emission spectroscopy. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Acidity (as HCl) | Acid-Base Titration | Neutralizes acidic impurities with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or phase separation against established reference standards. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing of the crucible residue. |
| Specific Optical Rotation | Polarimetry | Measures degree of rotation of plane-polarized light induced by chiral impurities or enantiomeric excess. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles suspended in dispersant by measuring angular scattering intensity of laser beam. |
| Thermal Stability | TGA | Monitors mass loss versus temperature under controlled atmosphere to assess decomposition onset and residual char content. |
