Bromocyclopentane (CAS 137-43-9), also known as Cyclopentyl Bromide, is a fascinating organic compound with a straightforward yet highly versatile chemical profile. As an alkyl halide, it possesses a unique reactivity that makes it a cornerstone for various synthesis applications across multiple industries. Understanding its core properties and how it functions in chemical reactions is crucial for chemists, researchers, and procurement specialists looking to leverage its potential.

The chemical formula of Bromocyclopentane is C5H9Br, and its molecular weight is approximately 149.03 g/mol. Physically, it is typically described as a colorless to pale yellow liquid. Key physical properties include a density around 1.39-1.47 g/cm³ and a boiling point of approximately 137-139 °C at standard atmospheric pressure. Its flash point is around 35-42 °C, indicating it is a flammable liquid and requires appropriate handling procedures.

The reactivity of Bromocyclopentane is primarily attributed to the bromine atom, which is a good leaving group. This characteristic makes it an excellent substrate for nucleophilic substitution reactions (SN1 and SN2). When reacted with strong nucleophiles, the bromine atom can be replaced by other functional groups, allowing for the introduction of the cyclopentyl moiety into a wide array of organic molecules. This versatility is fundamental to its role as an intermediate.

A prime example of its synthetic utility is the formation of the cyclopentyl Grignard reagent. Reacting Bromocyclopentane with magnesium metal in an anhydrous solvent like diethyl ether or tetrahydrofuran yields this organometallic compound. Cyclopentyl Grignard reagent is a powerful tool for forming new carbon-carbon bonds, essential for building complex molecular frameworks found in pharmaceuticals, fine chemicals, and even some advanced materials. When you need to buy Bromocyclopentane for Grignard reactions, ensuring its anhydrous nature and high purity from a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. is critical for successful outcomes.

Beyond Grignard chemistry, Bromocyclopentane is also used in other coupling reactions and as a starting material for creating functionalized cyclopentanes. For example, it can be a precursor for cyclopentanecarboxylic acid derivatives or serve as a building block in the synthesis of specific heterocyclic compounds. The ability to buy Bromocyclopentane from a trusted supplier in China ensures consistent quality for these demanding applications.

In summary, Bromocyclopentane (CAS 137-43-9) is a vital organic intermediate due to its inherent chemical properties and reactivity. Its capacity to undergo nucleophilic substitutions and form Grignard reagents makes it indispensable in many synthesis pathways. For manufacturers and researchers seeking this crucial compound, partnering with a reputable supplier that provides high-purity Bromocyclopentane at a competitive price is a strategic advantage.
