Overview

The simplest methyl ester, combining a methanoyl group with methoxy oxygen.

Its carbonyl carbon bears hydrogen, but is also bonded to the ester oxygen. That connectivity makes it a methanoate ester rather than an aldehyde. Hydrolysis gives methanol and methanoic acid or methanoate, depending on the conditions.
