1,1-(Ethylenedioxy)-3-bromopropane(CAT: R020179) is an organic compound featuring a protected diol in the form of an ethylenedioxy acetal linked to a three-carbon chain terminated with a bromine atom. The ethylenedioxy group serves as a stable protecting group for carbonyl functionalities, while the bromopropyl moiety provides a reactive alkyl halide site for nucleophilic substitution and other carbon–carbon or carbon–heteroatom bond-forming reactions. This combination makes it a versatile intermediate in organic synthesis, particularly in the preparation of functionalized ethers, heterocycles, and fine chemicals. It is commonly used in pharmaceutical, agrochemical, and materials research for constructing more complex molecular architectures.
