For researchers in material science and organic electronics, the precise specifications of chemical intermediates are paramount to the success of their experiments and product development. 2-Bromo-3-dodecylthiophene (CAS 139100-06-4) is a compound of significant interest, widely utilized in the synthesis of advanced organic semiconductors, particularly for OLEDs and organic photovoltaic cells. Understanding its key properties, such as purity, molecular formula, and physical characteristics, is crucial for effective utilization and for making informed purchasing decisions when you need to buy this material.

The chemical identity of 2-Bromo-3-dodecylthiophene is defined by its molecular formula, C16H27BrS, and its molecular weight of approximately 331.35 g/mol. These fundamental parameters ensure that researchers are working with the correct compound. However, the most critical specification for its application in high-performance electronics is its purity. We consistently supply 2-Bromo-3-dodecylthiophene with a minimum purity of 98% (as determined by Gas Chromatography - GC). This high level of purity is non-negotiable, as even minor impurities can act as charge traps or quenching sites, drastically reducing the efficiency and lifetime of the final electronic devices. For R&D purposes, higher purity often translates to more reliable and reproducible results.

Beyond purity, its physical properties provide practical insights for handling and processing. 2-Bromo-3-dodecylthiophene typically presents as a light yellow liquid. Its boiling point (around 165 °C at 0.2 mmHg) and density (approximately 1.13 g/cm³) are important parameters for chemists involved in reaction design and purification processes. The presence of the long dodecyl chain is a key feature, imparting excellent solubility in common organic solvents. This characteristic is vital for solution-based processing techniques, which are central to the low-cost manufacturing of flexible electronic devices like OLED displays and organic solar cells.

The reactivity of 2-Bromo-3-dodecylthiophene stems from the bromine atom, which readily participates in metal-catalyzed cross-coupling reactions. This makes it an ideal monomer for creating conjugated polymers and complex organic molecules. Researchers often use it in Suzuki, Stille, or Negishi coupling reactions to build extended pi-conjugated systems that exhibit desirable semiconducting or luminescent properties. The choice of reaction conditions and co-monomers allows for fine-tuning of the electronic and optical characteristics of the final material, enabling the development of devices with specific performance targets.
