Industrial Applications of 2-BROMO-5-BENZOYLTHIOPHENE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate in the synthesis of the antiplatelet drug ticagrelor | Undergoes palladium-catalyzed cross-coupling with amines to construct the thienopyrimidine core structure |
| Organic Synthesis | Used to build novel functional molecules containing brominated thiophene heterocycles | After lithium–halogen exchange, reacts with electrophiles (e.g., aldehydes, ketones, CO₂) or participates in metal-catalyzed coupling reactions such as Suzuki and Heck couplings |
| Materials Science | Building block for organic semiconductor materials in OLEDs and organic field-effect transistors (OFETs) | Introduced into conjugated polymer backbones via Stille or Suzuki coupling to tune HOMO/LUMO energy levels and charge-carrier transport properties |
Manufacturing Quality Control of 2-BROMO-5-BENZOYLTHIOPHENE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and visible impurities under natural light or standard illumination. |
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with UV detection (e.g., 254 nm), quantitatively analyze the target compound by comparing retention time and peak area with those of a reference standard. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Utilize ¹H-NMR and ¹³C-NMR to analyze molecular structure, confirming that the chemical environments of hydrogen and carbon atoms match the expected structure. |
| Molecular Weight Confirmation | Mass Spectrometry (MS) | Determine the molecular ion peak using electrospray ionization (ESI) or electron impact ionization (EI-MS), verifying whether the measured molecular weight matches the theoretical value for C₁₁H₇BrOS (approximately 266.14 g/mol). |
| Solubility | Solubility Test | Add the sample to solvents such as water, ethanol, ethyl acetate, and dichloromethane, shake thoroughly, and observe dissolution behavior to determine the applicable solvent range. |
| Water Content | Karl Fischer Titration | Quantitatively determine moisture content via the reaction between iodine and sulfur dioxide in pyridine and methanol, suitable for trace water analysis. |
| Residual Solvents | Gas Chromatography (GC) | Use a capillary column with a flame ionization detector (FID) to detect residual organic solvents from production processes (e.g., methanol, ethanol, acetone, dichloromethane). |
| Melting Point | Melting Point Determination | Use an automatic or capillary melting point apparatus to heat the sample and record initial and final melting temperatures, used for identification and purity assessment. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, measure residual levels of heavy metals such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopoeial or safety standards. |
| Related Substances (Impurities) | HPLC (Gradient Elution) | Optimize gradient elution conditions to separate the main peak from impurity peaks, detecting synthesis by-products or degradation products to evaluate sample stability and safety. |
