4-Chloro-2-ethylthiophene

Description:

4-Chloro-2-ethylthiophene is an organic compound characterized by its thiophene ring, which is a five-membered aromatic heterocycle containing sulfur. The presence of a chlorine atom at the 4-position and an ethyl group at the 2-position contributes to its unique chemical properties. This compound typically appears as a colorless to pale yellow liquid and has a distinctive odor. It is soluble in organic solvents, such as ethanol and ether, but has limited solubility in water due to its hydrophobic nature. 4-Chloro-2-ethylthiophene is primarily used in organic synthesis and may serve as an intermediate in the production of various pharmaceuticals, agrochemicals, and other fine chemicals. Its reactivity is influenced by the electron-withdrawing effect of the chlorine atom, which can enhance electrophilic substitution reactions. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested, and proper storage conditions should be maintained to prevent degradation.
