D-(+)-Lactide(CAT: R030370) is the cyclic dimer of D-lactic acid and serves as a key monomer for producing biodegradable polymers such as poly(D-lactide) (PDLA) and poly(D,L-lactide) (PDLLA). With its well-defined stereochemistry, D-(+)-lactide enables the synthesis of polymers with tailored crystallinity, degradation profiles, and mechanical strength. Its high purity and controlled reactivity make it an essential intermediate in biomedical materials research, including drug delivery systems, tissue engineering scaffolds, and resorbable implants. As a chiral building block, D-(+)-lactide is also used in copolymerization with glycolide or ε-caprolactone to create versatile bioresorbable materials for advanced medical and pharmaceutical applications.
