Methyl 2-hexenoate Usage And Synthesis

Description

Methyl 2-hexenoate has a green, musty, earthy, sweet, fruity odor with a very powerful, sharp, green-fruity flavor. May be prepared by boiling the corresponding acid with methanol in the presence of concentrated H2S04 in chloroform and subsequent elimination of water from the vapors using MgS04; also from 3-chloropropionic acid methyl ester and anhydrous sodium acetate in acetic acid.

Chemical Properties

Methyl 2-hexenoate has a green, musty, earthy, sweet, fruity odor and a very powerful, sharp, green-fruity flavor

Occurrence

Reported found in papaya, peas, soursop and mountain papaya

Uses

Methyl 2-hexenoate is used in flavor compositions for the type of fruit flavor demanding a rather sharp and green fruity topnote, such as Pineapple, Strawberry, etc. and in various fruit complexes. It is quite powerful, and the concentration used is normally equivalent to only 0.05 to 0.1 ppm in the finished product.

Definition

ChEBI: Methyl 2E-hexenoate is a fatty acid ester.

Preparation

By boiling the corresponding acid with methanol in the presence of concentrated H2SO4 in chloroform and subsequent elimination of water from the vapors using MgSO4; also from 3-chloropropionic acid methyl ester and anhydrous sodium acetate in acetic acid
