Description

Allyl bromide (CAS 106-95-6 ) is a reactive alkylating agent used primarily as a chemical building block in pharmaceutical synthesis and specialty chemical manufacturing. Known commercially as 3-bromopropene, it introduces the allyl group into target molecules. This process occurs through nucleophilic substitution reactions, enabling the construction of complex active pharmaceutical ingredients and fine chemicals. In pharmaceutical manufacturing, it serves as a key intermediate in synthesizing APIs. This is particularly useful where allylation of nitrogen, oxygen, or sulfur nucleophiles is required. Biotechnology and life sciences researchers use it to functionalize biomolecules and synthesize allylated nucleosides or amino acid derivatives. These materials are often used for research-scale production. The compound also supports the manufacture of agrochemical intermediates and specialty monomers where controlled allyl group incorporation is critical to the target structure. Quaternary ammonium biocides with allyl functionality are produced using this substance as the alkylating precursor. The product is supplied as a liquid, typically in stabilized form to prevent premature polymerization during storage. It is available in technical and high-purity grades to meet the requirements of pharmaceutical intermediate synthesis and research applications. This ensures compatibility with various industrial and laboratory protocols. Standard packaging ranges from small laboratory quantities through to bulk drum supply for industrial-scale production. All batches are tested to ensure they meet rigorous internal quality standards and customer specifications. Contact us for supply of Allyl bromide Request Quote
