CAS 4511-42-6: L-Lactide

Description: L-Lactide, with the CAS number 4511-42-6, is a cyclic diester derived from lactic acid, specifically the L-isomer. It is a colorless, crystalline solid that is soluble in organic solvents but has limited solubility in water. L-Lactide is a key monomer in the production of polylactic acid (PLA), a biodegradable polymer widely used in packaging, biomedical applications, and 3D printing. The substance exhibits a melting point that allows it to be processed easily in various applications. L-Lactide is known for its biocompatibility and biodegradability, making it an environmentally friendly alternative to petroleum-based plastics. Its polymerization can be initiated through various methods, including ring-opening polymerization, leading to the formation of high molecular weight PLA. Additionally, L-Lactide can undergo stereochemical transformations, influencing the properties of the resulting polymer, such as crystallinity and thermal behavior. Overall, L-Lactide plays a significant role in sustainable materials science and is a focus of research in green chemistry.
