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. |
|
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. |
