Methyl 3-[(2,2-dimethylbutanoyl)thio]propanoate

Methyl 3-[(2,2-dimethylbutanoyl)thio]propanoate (CAS 938063-63-9) is a thioester-functionalized building block used in pharmaceutical synthesis and biotechnology research. Its reactive thioester linkage makes it a practical substrate for enzyme-catalyzed reactions. In pharmaceutical intermediate synthesis, it supports the construction of complex molecules requiring controlled acyl-transfer chemistry under mild conditions. Biochemical research programs use it as a substrate to evaluate thioesterase activity.

The compound is particularly useful in pathway characterization work and acyltransferase enzyme studies. It also serves in the development of prodrug architectures where a cleavable thioester moiety is required for controlled release. This chemical allows for the precise release of the active acid component in various biological systems. It is supplied as a liquid or neat compound at research and development scale for laboratory use.
