CAS 206768-21-0: 2-Thiophenecarboxaldehyde,5-ethynyl-

Description: 2-Thiophenecarboxaldehyde, 5-ethynyl- is an organic compound characterized by the presence of a thiophene ring, which is a five-membered aromatic heterocycle containing sulfur. This compound features a carboxaldehyde functional group (-CHO) attached to the thiophene ring, along with an ethynyl group (-C≡CH) at the 5-position. The presence of the ethynyl group introduces a triple bond, contributing to the compound's reactivity and potential applications in organic synthesis and materials science. The thiophene moiety imparts aromatic stability and can participate in various chemical reactions, such as electrophilic substitutions. Additionally, the compound may exhibit interesting electronic properties due to the conjugation between the thiophene and ethynyl groups. Its unique structure makes it a candidate for use in the development of organic semiconductors, dyes, or as an intermediate in the synthesis of more complex organic molecules. As with many organic compounds, handling should be done with care, considering potential toxicity and reactivity.
