Description

3,3-Dimethylallyl Bromide is a versatile and reactive alkyl halide building block essential for organic synthesis. Its primary value lies in its ability to introduce the prenyl (3,3-dimethylallyl) group, a key structural motif found in numerous natural products and pharmaceuticals. This compound is critically needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of prenylated flavonoids, terpenoids, and other bioactive molecules.
• Agrochemical Synthesis: Used in the production of certain pesticides and plant growth regulators that incorporate the prenyl moiety.
• Fine Chemical Manufacturing: Serves as an alkylating agent in the preparation of specialty chemicals, flavors, and fragrances.
• Material Science Research: Employed in the development of novel polymers and functional materials through controlled polymerization or cross-linking reactions.
• Natural Product Synthesis: Crucial for the laboratory synthesis and structural modification of natural products containing isoprenoid units.
• Cross-Coupling Reactions: Acts as an electrophilic partner in various metal-catalyzed cross-coupling reactions to form carbon-carbon bonds.

Quality Control

Our 3,3-Dimethylallyl Bromide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and NMR analysis, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Keep away from strong bases and incompatible materials.
