Key Applications

• Organic synthesis reagent: Widely employed in Simmons-Smith-type cyclopropanation of alkenes and related carbene-transfer reactions.

• Specialty solvent: Serves as a dense, non-flammable solvent for selected extraction and reaction media where high density and moderate polarity are required.

• Methylenedioxy intermediate: Used to convert catechols and polyols into the corresponding methylenedioxy derivatives for fragrance, pharmaceutical and agrochemical building blocks.

• NMR internal standard: Functions as a convenient proton reference compound in certain spectroscopic analyses.

• Brominated intermediate: Acts as a versatile C1 source for further functionalization in the preparation of other specialty bromo compounds.
