Bromo(cyclopentyl)magnesium(CAS: 33240-34-5)

Bromo(cyclopentyl)magnesium is a colorless to pale yellow liquid. Its molecular weight is approximately 125.11 g/mol. This compound is sparingly soluble in water but highly soluble in ether and other organic solvents. It is highly reactive, particularly towards water, which can lead to the formation of cyclopentanol and magnesium bromide.

Bromo(cyclopentyl)magnesium can be synthesized by reacting bromo(cyclopentyl)iodide with magnesium in an ether solvent. The reaction is typically carried out at low temperatures and in the presence of a catalytic amount of iodine to improve the yield and regioselectivity of the product.

Bromo(cyclopentyl)magnesium, due to its reactivity, is primarily used in the pharmaceutical and polymer industries for the synthesis of various organic compounds. It can also be utilized in the development of new materials and sensors.

Handling Bromo(cyclopentyl)magnesium requires strict safety measures. It should be stored in a closed container and away from water and moisture. Personal protective equipment (PPE) such as gloves, goggles, and a lab coat is essential. Fume hoods should be used during handling to avoid inhalation. In case of a spill, neutralize with an appropriate absorbent and dispose of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling instructions.
