What is Allyl bromide?
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. Also known commercially as 3-bromopropene.
Where is Allyl bromide used?
- Pharmaceutical manufacturing: key intermediate in synthesizing APIs
- Biotechnology and life sciences: functionalizing biomolecules and synthesizing allylated nucleosides or amino acid derivatives
- Agrochemical intermediates and specialty monomers: controlled allyl group incorporation
- Quaternary ammonium biocides: alkylating precursor
- It introduces the allyl group into target molecules through nucleophilic substitution reactions.
Good to know: Stabilized form prevents premature polymerization during storage. Technical and high-purity grades meet requirements of pharmaceutical intermediate synthesis and research applications.
Commercial specifications
- Technical and high-purity grades
- Packaging from small laboratory quantities to bulk drums
- Batches tested to internal quality standards and customer specifications
