Meso-Lactide (Cat No.:C000701) is a cyclic ester compound commonly used in the production of polylactic acid (PLA), a biodegradable and biocompatible polymer. Meso-Lactide is a key building block in the synthesis of PLA, which finds applications in various fields, including bioplastics, medical implants, and drug delivery systems. Due to its chirality, meso-lactide lacks optical activity, making it distinct from other lactide stereoisomers.
