Product Description:

D(+)-Lactide is a cyclic diester, specifically the dimer of L-lactic acid. It is a white crystalline solid and exists as a stereoisomer. This compound is a key monomer in the synthesis of high molecular weight, stereoregular poly(L-lactic acid) (PLLA), a biodegradable and biocompatible polymer. The primary and most significant application of D(+)-lactide is as the fundamental building block for producing PLLA via ring-opening polymerization (ROP). PLLA is a crucial material in the fields of biomedical engineering (e.g., absorbable sutures, drug delivery systems, tissue engineering scaffolds) and environmentally friendly plastics. Its controlled stereochemistry is essential for achieving polymers with specific mechanical and degradation properties. While its dominant role is as a polymer precursor, D(+)-lactide also serves as a specialized organic synthesis building block in research, particularly for introducing lactic acid-derived chiral units into more complex molecules or for studying polymerization mechanisms.
