1,4-Dioxacyclo-2,5-hexanedione is a cyclic ester formed by the dehydration of two molecules of glycolic acid, and is a monomer used to prepare polyglycolic acid (PGA). It is mainly used as an intermediate in organic synthesis.

Polyglycolic acid is an important biodegradable polyester material. Under the catalysis of biological enzymes, it can be degraded into glycolic acid and participate in the metabolism of the human body.

Therefore, polyglycolic acid is widely used in biomedical materials such as surgical sutures, artificial tissues, and drug controlled release. Such as surgical sutures, artificial skin and blood vessels, bone fixation and repair, controlled drug release, tissue engineering, etc.
