D-lactide is the dextrorotatory form of lactide, which is a cyclic diester derived from the condensation of two molecules of lactic acid. The “D” refers to the configuration of the molecule that is based on the orientation of the functional groups around the chiral center in the lactic acid from which it is derived. This configuration is related to the molecule’s ability to rotate plane-polarized light to the right, which is a characteristic of dextrorotatory compounds.

In the context of polymers, D-lactide can be polymerized to form poly-D-lactic acid (PDLA), which is a stereospecific form of polylactic acid (PLA). This polymer has unique properties, such as a high degree of crystallinity and a higher melting point compared to the racemic forms of PLA, which are derived from a mixture of D- and L-lactide.

D-lactide is used in various applications, particularly in the medical field for biodegradable implants, sutures, and drug delivery systems due to its biocompatibility and biodegradability. The properties of the polymer can be tailored by adjusting the ratio of D-lactide to L-lactide in the material, allowing for a wide range of uses in both medical and industrial applications.
