3-(2-Ethylhexyl)thiophene (CAS No.: 121134-38-1) is a fascinating organic compound whose specific chemical properties make it highly valuable across several advanced technological sectors. As a leading chemical supplier, NINGBO INNO PHARMCHEM CO.,LTD. provides this critical intermediate, ensuring access to essential materials for innovation. Understanding its characteristics is key to appreciating its role in fields like organic electronics.

At its core, 3-(2-Ethylhexyl)thiophene is a derivative of thiophene, a five-membered heterocyclic aromatic ring containing sulfur. The attachment of a branched alkyl chain, specifically the 2-ethylhexyl group, at the third position of the thiophene ring is what gives this compound its unique attributes. This structural modification is not arbitrary; it significantly enhances the compound's solubility in common organic solvents. This improved solubility is a critical factor for processing the material into thin films, which is a fundamental requirement for its applications in organic electronics, such as in the synthesis of OFET polymer precursor materials.

The molecular weight of 3-(2-Ethylhexyl)thiophene is approximately 196.35 g/mol, and it typically presents as a liquid with a density around 0.915 g/mL. Its boiling point is noted at 150-152°C at 7.5 Torr, and its flash point is greater than 110°C, indicating reasonable stability under standard handling conditions. For users looking to buy this chemical, these physical properties are essential for safe storage and handling, especially when considering large-scale applications.

As a monomer, 3-(2-Ethylhexyl)thiophene is instrumental in the polymerization processes that create conjugated polymers. These polymers, often referred to as poly(3-alkylthiophene)s when derived from similar structures, exhibit semiconducting properties due to the delocalized pi-electron system along their backbone. This makes them ideal for use in devices like Organic Field-Effect Transistors (OFETs), Organic Light-Emitting Diodes (OLEDs), and Organic Photovoltaics (OPVs). The specific nature of the ethylhexyl side chain can influence the polymer's morphology and intermolecular packing, thereby affecting charge carrier mobility and device performance. This is why sourcing a high-purity organic semiconductor monomer is crucial for predictable outcomes.
