ethynylcyclopentane

Description:
Ethynylcyclopentane, with the CAS number 930-51-8, is an organic compound characterized by its unique structure that includes a cyclopentane ring and an ethynyl group (–C≡C–). This compound is a colorless liquid at room temperature and is known for its distinctive alkyne functional group, which imparts notable reactivity, particularly in addition reactions. Ethynylcyclopentane exhibits moderate volatility and is relatively insoluble in water, but it is soluble in organic solvents such as ethanol and ether. Its molecular structure contributes to its physical properties, including a specific boiling point and density that are typical of small cyclic hydrocarbons. Ethynylcyclopentane is of interest in organic synthesis and materials science, where it may serve as a building block for more complex molecules or polymers. Safety considerations include handling it in well-ventilated areas and using appropriate personal protective equipment, as it may pose health risks if inhaled or ingested.
