1. Pharmaceuticals

• Synthesis of Drug Intermediates: Allyl bromide is used to introduce allyl groups (–CH₂CH=CH₂) into molecules, which enhances biological activity or provides reactive sites for further derivatization.
• Precursor for CNS Agents and Antivirals: Allyl-substituted compounds often show neuroactive or antiviral properties, and allyl bromide acts as a key intermediate in synthesizing these molecules.
• Formation of Allylamines and Allyl Esters: These derivatives are used in drugs with anti-inflammatory or antineoplastic properties.

2. Agrochemicals

• Synthesis of Pesticides and Fungicides: Used in the manufacture of allyl-based pesticides due to the double bond's ability to interact with biological systems and disrupt enzymes.
• Herbicide Additive Manufacturing: Allyl groups increase hydrophobicity, improving penetration into plant tissues.

3. Performance Chemicals

• Allylating Agent for Organic Molecules: A key reagent for synthesizing allyl ethers, allyl esters, and allyl amines, which are used in fragrances, resins, lubricants, and chemical intermediates.
• Flavor and Fragrance Industry: Used to synthesize allyl phenols, which are ingredients in perfumes and flavorings (e.g., eugenol derivatives).

4. Polymers & Resins 

• Crosslinking Agent: Allyl bromide is used to incorporate unsaturated allyl groups into polymer backbones, allowing for UV-curing, peroxide curing, and copolymerization.
• Resin Modifier: Used in the manufacture of allyl resins and allyl-functional monomers, which impart thermosetting properties, chemical resistance, and flexibility.
• Functional Monomer Synthesis: Key precursor for specialty polymers like poly(allyl glycidyl ether) and crosslinkable epoxies.

 5. Fabric Solutions

• Intermediate for Functional Dyes: Allyl bromide is used to synthesize allylated dye precursors, which improve binding to fabrics and enhance lightfastness through better anchoring.
• Reactive Dye Formation: Allyl groups allow covalent attachment to cellulose and synthetic fibers under mild conditions.

6. Paint, Coatings & Adhesives

• Crosslinkable Additive in Coatings: Allyl bromide derivatives are introduced into acrylic or epoxy resins to improve adhesion and mechanical flexibility.
• Intermediate for Flexible Adhesives: Used in the manufacture of rubbery or pressure-sensitive adhesives by allowing post-polymerization curing through the allyl group.
