Butanefrine or ethylnorepinephrine

Methyl 3-butenoate is an olefin ester. It is reported to undergo Iron carbonyl-promoted isomerization to afford &#945, &#946-unsaturated esters.

Application Nonanenitrile was used as an organic nitrogen standard in the determination of a quantitative method for the speciation of ON within ambient atmospheric aerosol .
