Application

Diethyl sulfite serves as a versatile alkylating agent and sulfur source in organic synthesis, particularly for introducing sulfite groups into molecular frameworks. It finds application as a stabilizer in polymer chemistry and as an intermediate in pharmaceutical manufacturing. Researchers also employ it as a mild reducing agent in selective transformations where stronger reductants would cause side reactions.
