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.

Compatible with the following:

Scanning tunneling microscopy (STM) topographical images and inelastic electron tunneling spectra (IETS) of a cis-2-butene molecule adsorbed on a Pd(110) surface have been simulated by first-principles calculations. Calculations have eliminated the ambiguity between the STM image and the adsorption orientation
