4-Bromo-1-butanol丨CAS 33036-62-3

4-Bromo-1-butanol is a versatile halogenated alcohol widely used as an intermediate in organic synthesis, pharmaceutical development, and materials chemistry. Its dual functionality, featuring both a bromine atom and a hydroxyl group, allows selective reactions in nucleophilic substitution, esterification, and etherification processes. It is commonly applied in the synthesis of heterocyclic compounds, pharmaceuticals, agrochemicals, and fine chemicals, where the bromide can be replaced or elaborated into functional groups while the hydroxyl provides a reactive handle for further modification. In medicinal chemistry, 4-bromo-1-butanol is used to prepare intermediates for drug candidates, enzyme inhibitors, and bioactive molecules. It is also employed in polymer and material research for the synthesis of functionalized monomers and crosslinking agents.

The benefits of 4-bromo-1-butanol arise from its bifunctional reactivity, chemical stability, and ease of handling. The bromide moiety allows efficient substitution reactions, enabling incorporation of diverse nucleophiles to construct complex molecules. The hydroxyl group provides additional sites for derivatization, such as esterification or ether formation, increasing synthetic flexibility. The compound is relatively stable under normal storage conditions, soluble in common organic solvents, and compatible with various reaction conditions, supporting reproducible and scalable synthesis. These features make it an efficient intermediate for multi-step organic syntheses, enabling high-yield transformations and precise functionalization.
