3-Dodecylthiophene(CAS: 104934-52-3)

3-Dodecylthiophene is a liquid at room temperature with a characteristic aroma. It has a molecular weight of approximately 238.37 g/mol. The compound is poorly soluble in water but soluble in organic solvents such as benzene and toluene. It is moderately reactive, particularly towards protonation and oxidation.

3-Dodecylthiophene is typically synthesized via the alkylation of thiophene with 1-dodecene in the presence of a Lewis acid catalyst, such as aluminum trichloride, under reflux conditions. The reaction yields a thiophene derivative with high selectivity and good yield.

3-Dodecylthiophene is used in the production of functionalized polymers, particularly for electronic applications, and as a precursor in the synthesis of thiophene derivatives for use in pharmaceuticals and semiconductors. It is also utilized in the development of sensors due to its unique electronic properties.

When handling 3-dodecylthiophene, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be handled according to standard chemical spill procedures. Always refer to the Safety Data Sheet (SDS) for detailed handling and safety information.
