cis-2,3-Epoxybutane

Description:
Cis-2,3-epoxybutane, with the CAS number 1758-33-4, is a cyclic ether characterized by its three-membered epoxide ring structure. This compound is derived from butane, featuring an epoxy group at the 2 and 3 positions, which introduces significant strain due to the angle strain inherent in the three-membered ring. As a result, cis-2,3-epoxybutane is reactive, particularly towards nucleophiles, making it useful in various chemical synthesis applications. The "cis" designation indicates that the substituents on the double bond are on the same side, influencing its stereochemistry and reactivity. This compound is typically colorless and has a distinctive odor. It is soluble in organic solvents but has limited solubility in water. Due to its reactivity, cis-2,3-epoxybutane can participate in ring-opening reactions, leading to the formation of various derivatives. Safety precautions are necessary when handling this compound, as it can be hazardous due to its potential to cause irritation and its reactivity with biological molecules.
