Cas no 62323-44-8 (2-bromo-5-ethylthiophene)
2-Bromo-5-ethylthiophene is a brominated thiophene derivative featuring an ethyl substituent at the 5-position. This compound serves as a versatile intermediate in organic synthesis, particularly in the preparation of functionalized thiophenes for pharmaceuticals, agrochemicals, and materials science. The bromine moiety allows for further functionalization via cross-coupling reactions, such as Suzuki or Stille couplings, while the ethyl group enhances lipophilicity, influencing solubility and reactivity. Its well-defined structure and stability under standard conditions make it a reliable building block for heterocyclic chemistry. Suitable for use in controlled environments, it requires handling with appropriate safety precautions due to its halogenated nature.
