D-(+)-Lactide（Cat No.:R030370）is a chiral, cyclic diester derived from two molecules of D-lactic acid, with the molecular formula C6H8O4. It appears as a white crystalline solid and serves as a key monomer in the production of poly(D-lactic acid) (PDLA), a biodegradable polymer used in biomedical devices, sutures, and environmentally friendly packaging materials. D-(+)-Lactide undergoes ring-opening polymerization to form high-molecular-weight polymers with desirable mechanical and degradation properties. Due to its purity and stereochemistry, it enables the formation of stereocomplexes with L-lactide. It should be stored in a dry, cool environment.
