Industrial Applications of 3-BROMO-4-METHYLTHIOPHENE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate in the synthesis of the antiplatelet drug ticagrelor | Forms a C–N bond via palladium-catalyzed cross-coupling with 4-chloro-7H-pyrrolo[2,3-d]pyrimidine, followed by multi-step functional group transformations to complete the total synthesis of ticagrelor |
| Organic Electronic Materials | Used to prepare thienyl-based conjugated polymers and small-molecule donor materials for organic photovoltaics (OPV) | Serves as a structural building block in Stille or Suzuki coupling polymerizations; the bromine atom enables subsequent metal-catalyzed couplings, while the methyl group enhances molecular planarity and charge-carrier mobility |
| Pesticide Development | Structural modification intermediate for novel insecticides and fungicides | Generates bioactive thiophene-containing molecular scaffolds via lithium–halogen exchange followed by addition to aldehydes/ketones, or via Suzuki coupling with boronic esters |
Manufacturing Quality Control of 3-BROMO-4-METHYLTHIOPHENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents based on partitioning into headspace and GC separation. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies trace metal impurities by atomic emission intensity after high-temperature plasma atomization. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using ion-exchange column and conductivity detection. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against standard reference under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Measures acidic impurities by neutralization with standardized sodium hydroxide solution using phenolphthalein indicator. |
