Industrial Applications of 2-Ethylthiophene
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate in the synthesis of the antiplatelet drug ticagrelor | Constructs the thiophene ring side chain via multi-step organic synthesis, including bromination and coupling reactions |
| Agrochemical Intermediates | Heterocyclic building block for novel insecticides and fungicides | Introduced as a substituent in thiophene-based agrochemical molecules, participating in electrophilic substitution or metal-catalyzed coupling reactions |
| Organic Optoelectronic Materials | Building block for hole-transport materials in organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs) | Incorporated into conjugated polymer backbones via Suzuki or Stille coupling reactions to modulate HOMO energy levels and charge-carrier mobility |
Manufacturing Quality Control of 2-Ethylthiophene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and flame ionization detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system; endpoint detected amperometrically. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator or potentiometric endpoint detection. |
| Residue on Ignition | Gravimetric Analysis | Sample is ignited at 700-800 C to oxidize organic matter; residue mass is measured after cooling in a desiccator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample color against platinum-cobalt standard solutions or measurement of absorbance at 455 nm using a spectrophotometer. |
| Density at 20 C | Digital Density Meter | Measurement of oscillating U-tube frequency change induced by sample density, calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Determination based on Snell's law by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Boiling Point Range | Distillation (ASTM D1078) | Measurement of initial and final boiling points using a micro distillation apparatus under controlled heating and atmospheric pressure. |
| Sulfur Content | Combustion IC (Ion Chromatography) | High-temperature combustion converts sulfur to sulfate, followed by anion exchange separation and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of trace metal content after acid digestion and atomization in a graphite furnace or flame, measuring absorbance at characteristic wavelengths. |
| Non-Volatile Residue | Evaporation and Gravimetry | Sample is evaporated to dryness at 105 C, and residual mass is determined gravimetrically after cooling. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and semi-quantification of volatile odor-causing impurities via retention time and mass spectral library matching. |
