This chemical is a specialty reagent primarily used in organic synthesis to introduce cyclopropane structural motifs, which are key in many pharmaceuticals and agrochemicals. It functions as a precursor for cyclopropane derivatives, enabling the transfer of the 1-(ethoxycarbonyl)cyclopropyl group to electrophiles with high selectivity and efficiency. The compound is valuable for developing complex organic molecules, such as natural products and bioactive compounds. Its tetrafluoroborate counterion improves solubility and stability, allowing use across diverse reaction conditions.
