3-Mercapto-2-methylpenta-1-ol Usage And Synthesis

Chemical Properties

3-Mercapto-2-methylpentan-1-ol (racemic) is a highly odorous mercaptan with an onion or leek-like aroma. Flavor quality was reported to strongly depend on concentration.

Occurrence

Reportedly present in onion.

Definition

ChEBI: 3-Mercapto-2-methylpentanol is an alkanethiol.

Preparation

Prepared by a highly diastereoselective aldol reaction using a chiral auxiliary process with further derivatization yielding the enantiopure compound.

Aroma threshold values

At low concentrations (0.5 ppb), a pleasant, meat-broth, sweaty, onion and leek-like odor can be perceived.
