Product Description:

Allyl bromide is a colorless to pale yellow liquid with the chemical formula C_H_Br. It is an allylic halide featuring a reactive bromine atom attached to a terminal alkene, making it a highly versatile and widely used organic synthesis building block. As a key synthetic intermediate, allyl bromide serves as an efficient allylating agent in organic chemistry. It is extensively employed in the synthesis of pharmaceuticals, agrochemicals, and natural products, primarily through nucleophilic substitution reactions to introduce the allyl group. Additionally, it is a common reagent for the preparation of Grignard reagents and organozinc compounds, and it participates in cross-coupling reactions such as the Heck reaction. Due to its high reactivity, allyl bromide is a potent lachrymator and must be handled with care under a fume hood. It is typically stored in a cool, dark place to prevent polymerization and decomposition. Its industrial significance lies in its role as a fundamental building block for producing a vast array of more complex chemical entities.
