DL-Lactide (CAT: L046645) is the cyclic dimer of racemic lactic acid, composed of equal amounts of D- and L-isomers. Unlike optically pure D- or L-lactides, DL-lactide polymerizes to form amorphous poly(D,L-lactide) (PDLLA), which exhibits uniform degradation without crystalline residues. This unique property makes DL-lactide a critical monomer for synthesizing biodegradable polymers with predictable hydrolytic behavior. Widely applied in biomedical materials research, DL-lactide is used in developing drug delivery systems, resorbable implants, and tissue engineering scaffolds. Its versatility in copolymerization with glycolide or ε-caprolactone further expands its applications, enabling the design of advanced bioresorbable medical and pharmaceutical materials.
