Product Description:

Valeryl bromide, also known as pentanoyl bromide, is an organic compound with the molecular formula C5H9BrO. It is a colorless to pale yellow liquid with a pungent odor. Structurally, it is an acyl bromide, specifically the bromide derivative of valeric acid (pentanoic acid). This compound is primarily used as a versatile reagent in organic synthesis. Its main function is as an acylating agent, introducing the valeryl (pentanoyl) group into target molecules. It is particularly valuable for the synthesis of esters, amides, and acid anhydrides. Due to its high reactivity, it is often employed in peptide coupling reactions and in the preparation of various pharmaceutical intermediates and fine chemicals. It serves as a key building block for constructing more complex molecular architectures. Valeryl bromide is highly reactive, moisture-sensitive, and corrosive. It reacts violently with water, alcohols, and amines, releasing hydrogen bromide. Proper handling requires the use of appropriate personal protective equipment and anhydrous conditions.
