BOC-L-leucina

Descripción:

BOC-L-leucina, con el número CAS 13139-15-6, es un derivado del aminoácido leucina, que es esencial para la síntesis de proteínas y varios procesos metabólicos. Este compuesto presenta un grupo protector de tert-butilooxicarbonilo (BOC) unido al grupo amino de L-leucina, lo que lo hace útil en la síntesis de péptidos y en la química orgánica. BOC-L-leucina es típicamente un sólido cristalino blanco a blanco sucio, y es soluble en disolventes orgánicos como el diclorometano y el dimetilformamida, pero menos soluble en agua. El grupo BOC sirve para proteger la funcionalidad amino durante las reacciones químicas, permitiendo modificaciones selectivas de otros grupos funcionales. Tras la desprotección, BOC-L-leucina puede participar en reacciones adicionales para formar péptidos u otros derivados. Su estabilidad y reactividad lo convierten en un intermediario valioso en la síntesis de productos farmacéuticos y bioquímicos. Al igual que con muchas sustancias químicas, el manejo y almacenamiento adecuados son esenciales para mantener su integridad y garantizar la seguridad en entornos de laboratorio.

tert-Butoxycarbonyl-L-leucine

CAS: 13139-15-6

Tert-Butoxycarbonyl-L-leucine (tBOC-LL) is a tetrapeptide that is used as a drug substance in the synthesis of buserelin, a synthetic peptide hormone. It has been shown to have high reactivity in organic solvents and can be used in cationic polymerization reactions. tBOC-LL has been used to synthesize helical structures with high purity and yield. As it is not an amino acid, tBOC-LL does not occur naturally and must be synthesized.
