Application

cis-2-Butene is an unsaturated olefinic hydrocarbon used as a precursor in the polymerization of gasoline. It is also used to synthesize butadiene and other aliphatic C4/C5 organic molecules. It is also employed as a cross-linking agent.

Packaging

Supplied in a Sure/Pac cylinder and has a brass needle valve with a male 1/4" NPTF outlet thread installed. Before using the cylinder, ensure that the valve is closed, then remove the galvanized steel hex cap that seals the outlet valve.

The reactivation of organophosphorus compound (OP)-inhibited acetylcholinesterase (AChE) by oximes is inadequate in case of different OP nerve agents. This fact led to the synthesis of numerous novel oximes by different research groups in order to identify more effective reactivators.
