L-Lactida

Descripción:

L-Lactida, con el número CAS 4511-42-6, es un diéster cíclico derivado del ácido láctico, específicamente del isómero L. Es un sólido cristalino incoloro que es soluble en disolventes orgánicos pero tiene una solubilidad limitada en agua. L-Lactida es un monómero clave en la producción de ácido poliláctico (PLA), un polímero biodegradable ampliamente utilizado en envases, aplicaciones biomédicas e impresión 3D. La sustancia presenta un punto de fusión que permite procesarla fácilmente en diversas aplicaciones. L-Lactida es conocido por su biocompatibilidad y biodegradabilidad, lo que lo convierte en una alternativa ecológica a los plásticos derivados del petróleo. Su polimerización puede iniciarse a través de varios métodos, incluida la polimerización por apertura de anillo, lo que lleva a la formación de PLA de alto peso molecular. Además, L-Lactida puede experimentar transformaciones estereoquímicas, influyendo en las propiedades del polímero resultante, como la cristalinidad y el comportamiento térmico. En general, L-Lactida desempeña un papel significativo en la ciencia de materiales sostenibles y es un foco de investigación en química verde.

L-(-)-Lactide

CAS: 4511-42-6

L-(-)-lactide is a compound that consists of an intramolecular hydrogen bond between the hydroxyl group and the carbonyl group. It is used in the synthesis of poly(d,l-lactide) (PDLLA), which serves as a growth factor for cells in culture. The hydroxy groups on PDLLA can be polymerized using cationic polymerization to form poly(d, l-lactide) (PDLL). This polymer has been shown to have potential use as both a scaffold material for tissue engineering and a drug delivery system. FTIR spectroscopy has shown that L-(-)-Lactide has two distinct absorption peaks at 1350 cm-1 and 1410 cm-1. Both peaks are attributed to stretching vibrations of the carbonyl groups. These two peaks are also indicative of its intramolecular hydrogen bond with the hydroxyl group, where the peak at 1350 cm-
