Lactide - 4511-42-6

Key Functions: Food Contact & Additives, Pesticides & Biocides, Tech, Energy & Fuel

Lactide is the monomer used to synthesize polylactic acid, a biocompatible and biodegradable plastic (Futerro 2020). Lactide is produced by the oligomerization of lactic acid followed by cyclization. Lactide has two stereoisomer forms: L-lactide (CAS #45411-42-6) and D-lactide (CAS #13076-17-0). CAS #615-95-2 refers to a substance with no sterioisome designation (i.e., DL-lactide), and is also associated with the CAS #95-96-5.
