Description

Dl-Lactide CAS NO 95-96-5 is a high-purity cyclic dimer of lactic acid, serving as the essential monomer for the synthesis of polylactic acid (PLA) and other lactide-based polymers. This compound is critical for creating biodegradable and bio-based materials that meet modern sustainability demands. It is primarily sought by manufacturers in the bioplastics, medical device, pharmaceutical, and specialty chemical industries for applications ranging from compostable packaging to resorbable medical implants.

Application

• Primary monomer for Polylactic Acid (PLA) synthesis, a leading biodegradable polymer.
• Production of medical-grade polymers for resorbable sutures, drug delivery matrices, and orthopedic implants.
• Manufacture of high-performance, compostable packaging materials and films.
• Synthesis of specialty copolymers and polymer blends to tailor material properties like flexibility and degradation rate.
• Research and development of novel bio-based materials in academic and industrial laboratories.
• Intermediate in organic synthesis for producing chiral compounds and fine chemicals.
