| Hazard Information | Back Directory | [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. |
