Cyclopentyl Bromide (CAS 137-43-9) is a chemical compound that holds significant importance in the field of organic synthesis and chemical manufacturing. Characterized as a clear, colorless liquid, its utility stems from its reactive nature as an alkyl halide, making it an invaluable intermediate. Understanding its chemical properties and synthesis pathways is crucial for chemists, researchers, and procurement specialists looking to leverage its capabilities. As a prominent supplier, we aim to provide clarity on this essential compound and its industrial relevance.

Chemical Properties and Structure

The molecular formula for Cyclopentyl Bromide is C5H9Br, with a molecular weight of approximately 149.04 g/mol. The presence of the bromine atom attached to the cyclopentane ring makes it susceptible to nucleophilic substitution reactions (SN1 and SN2), as well as elimination reactions. Its boiling point typically falls between 135-138°C, and it is miscible with most organic solvents while exhibiting limited solubility in water due to its hydrophobic nature. These properties dictate its handling, storage, and application in various chemical processes.

Synthesis Pathways for Cyclopentyl Bromide

Cyclopentyl Bromide is commonly synthesized through the reaction of cyclopentanol with a brominating agent. Popular methods include using hydrobromic acid (HBr) in the presence of a catalyst like sulfuric acid, or employing phosphorus tribromide (PBr3). Another common route involves the free radical bromination of cyclopentane, though this can sometimes lead to a mixture of products. Manufacturers typically employ optimized, scalable processes to ensure high purity and yield. For industrial buyers, the efficiency and cost-effectiveness of the synthesis route directly impact the price of Cyclopentyl Bromide available for purchase.
