Description
Trans-2-Hexene (CAS 4050-45-7, EC 223-752-3) is a straight-chain six-carbon alkene with the double bond in the trans configuration at the second position. It is also referenced under the names NSC 74123 and (E)-2-Hexene. No E-code designation applies to this substance.
In plastics and polymer manufacturing, Trans-2-Hexene functions as a comonomer and polymerization initiator, where its reactive double bond is incorporated into polymer chains to modify molecular weight distribution and branching. In lubricant and fuel additive synthesis, it serves as a reactive carrier solvent, facilitating the controlled delivery of active components during blending operations.
Trans-2-Hexene is supplied as a liquid and is registered under REACH, making it compliant for industrial procurement within the European Economic Area. Buyers should confirm purity grade specifications directly with the supplier to match application requirements. Standard packaging formats for liquid alkenes of this type include drums and intermediate bulk containers.
