A type of organic compound that has two ester groups in its structure.
The chemist synthesized a diester for the experiment.
Diester is formed from "di-" (meaning two) and "ester" (from Latin "aestas", meaning summer, but in chemistry refers to a type of compound formed from an acid and an alcohol). The term "diester" refers to a compound that contains two ester groups.
Think of 'di-' meaning two, and 'ester' referring to a type of chemical compound. This helps you remember that a diester is a compound with two ester groups.
