Used primarily in the synthesis of biodegradable polymers, particularly poly(lactic-co-glycolic acid) (PLGA), which is widely applied in medical fields. It serves as a monomer for creating controlled-release drug delivery systems, sutures, and implants due to its biocompatibility and biodegradability. Additionally, it finds use in tissue engineering for scaffolding materials that support cell growth and regeneration. Its ability to degrade into non-toxic byproducts makes it suitable for environmentally friendly applications in packaging and agricultural films.
