4-Mercapto-4-methylpentan-2-one(Cas 19872-52-7) Usage

Chemical Composition and Structure

4-Mercapto-4-methyl-2-pentanone (4MMP) is an alkylthiol compound consists of a five-carbon chain with a methyl group at the 4-position and a mercapto group attached to the second carbon atom.

Production Methods

The precursor of 4MMP, cysteine-conjugate of 4MMP, can be synthesized using chemical methods. In addition, microbial cell extracts containing β-lyases, particularly from bacteria like Shewanella putrefaciens, are used to convert thiol precursors into 4MMP.

Definition

ChEBI: An alkylthiol that is 4-methylpentan-2-one substituted at position 4 by a mercapto group.

Aroma threshold values

Odor threshold in water, 0.0001 to 0.005 ppb (for 2-mercapto-2-methyl-4-pentanone).
