CAS 646-04-8: trans-2-Pentene

Description: Trans-2-pentene is an alkene with the molecular formula C5H10, characterized by a double bond between the second and third carbon atoms in its chain. As an isomer of pentene, it features a trans configuration, meaning that the substituents attached to the double bond are on opposite sides, which influences its physical properties. Trans-2-pentene is a colorless liquid at room temperature and has a slightly sweet odor. It is less dense than water and is insoluble in water but soluble in organic solvents. The compound is flammable and can participate in various chemical reactions typical of alkenes, such as hydrogenation, polymerization, and electrophilic addition. Its boiling point and melting point are influenced by the presence of the double bond and the overall structure of the molecule. Trans-2-pentene is used in organic synthesis and as an intermediate in the production of various chemicals. Safety precautions should be taken when handling this substance due to its flammable nature and potential health hazards.
