Used primarily as an intermediate in organic synthesis, this compound serves as a sulfonate ester that functions as a good leaving group in nucleophilic substitution reactions. It is commonly employed in the preparation of various pharmaceuticals, agrochemicals, and fine chemicals where controlled alkylation is required. Due to its reactivity profile, it facilitates the introduction of the sec-butyl moiety in target molecules under mild conditions. Its stability and ease of handling make it suitable for use in research laboratories and industrial processes involving route development and functional group transformations.
