3-Thiophenesulfonylchloride,2,5-dihydro-,1,1-dioxide(9CI)

Description:
3-Thiophenesulfonylchloride, 2,5-dihydro-, 1,1-dioxide, commonly referred to by its CAS number 112161-61-2, is a chemical compound characterized by its sulfonyl chloride functional group attached to a thiophene ring. This compound features a five-membered aromatic ring containing sulfur, which contributes to its unique reactivity and properties. The presence of the sulfonyl chloride group indicates that it can participate in nucleophilic substitution reactions, making it useful in organic synthesis, particularly for the introduction of sulfonyl groups into various substrates. Additionally, the 1,1-dioxide structure suggests that it has two oxygen atoms double-bonded to the sulfur atom, enhancing its electrophilic character. This compound is typically a solid at room temperature and may exhibit moderate to high solubility in polar organic solvents. Due to its reactive nature, it should be handled with care, as it can be corrosive and may pose hazards upon contact with moisture or reactive substances. Overall, 3-Thiophenesulfonylchloride is valuable in the synthesis of pharmaceuticals and agrochemicals.
