1-Ethynylcyclohexanol（Cat No.:R018100）is a multifunctional organic compound featuring both a tertiary alcohol and a terminal alkyne group on a cyclohexane ring. This dual functionality makes it a valuable intermediate in synthetic organic chemistry, particularly in the development of pharmaceuticals, agrochemicals, and specialty materials. It is often used in click chemistry, Sonogashira couplings, and cycloaddition reactions. The rigid cyclohexyl backbone provides structural stability, while the ethynyl moiety enables diverse transformations. Its reactivity and steric profile make it ideal for constructing complex molecules and bioactive scaffolds.
