The Preferred IUPAC Name (PIN) is diethyl propanedioate.


Step 1. Identify the highest priority functional group

This compound is an ester.

Step 2. Write the name of the ester

Esters are alkyl alkanoates.


(a) Name the alkyl group.

ethane - ane + ylethyl

b) Name the acid portion of the ester

This is a three-carbon acid.

propanoic acid - oic acid + oatepropanoate

There are two ester groups. We use the multiplying prefix di-.

The PIN of the ester is diethyl propanedioate.

The IUPAC retains the common name malonic acid, so diethyl malonate an acceptable (but not preferred) name.
