Cas no 533-68-6 (DL-Ethyl 2-bromobutyrate)

DL-Ethyl 2-bromobutyrate (CAS 533-68-6) is a brominated ester commonly used as an intermediate in organic synthesis. Its reactive α-bromo carbonyl structure makes it valuable for nucleophilic substitution reactions, enabling the introduction of butyrate derivatives in pharmaceuticals, agrochemicals, and specialty chemicals. The ethyl ester group enhances solubility in organic solvents, facilitating reactions under mild conditions. This compound is particularly useful in asymmetric synthesis and the preparation of chiral building blocks. Its stability under controlled storage conditions ensures consistent performance in multi-step synthetic processes. DL-Ethyl 2-bromobutyrate is typically handled under inert atmospheres to prevent degradation. Purity and precise bromination are critical for optimal reactivity in target applications.
