Lysine Diisocyanate
CAS Number: 39932-60-0
Lysine diisocyanate (LDI) is a bio-based aliphatic diisocyanate derived from L-lysine, offering a renewable alternative to petrochemical isocyanates such as HDI. LDI-based polyurethanes are used in biomedical applications, biodegradable scaffold materials, and eco-label coatings due to their excellent biocompatibility, low cytotoxicity, and aliphatic character providing UV stability.
