Used as a reagent in organic synthesis, particularly in hydroboration reactions where selective reduction of alkenes or alkynes is required. Its ethoxy and ethyl groups help modulate reactivity and solubility, making it useful in the preparation of boron-containing intermediates for pharmaceuticals and fine chemicals. Commonly employed in the synthesis of complex molecules where controlled borane delivery is needed. Also finds use in the development of new catalytic processes and in the modification of organic substrates for research applications.
