Descrizione generale

Dimethyl sulfite is an insect repellent and also experimentally identified as a mutagenic agent.

Applicazioni

The conformations and vibrational spectra of dimethyl sulfite was studied by matrix-isolation fourier transform infrared spectroscopy and to study its conformational selective aggregation. It may be used in organic synthesis.
