BOC-L-leucina

Descrizione:

BOC-L-leucina, con il numero CAS 13139-15-6, è un derivato dell'aminoacido leucina, essenziale per la sintesi proteica e vari processi metabolici. Questo composto presenta un gruppo protettivo tert-butilossicarbonilico (BOC) attaccato al gruppo amminico della L-leucina, rendendolo utile nella sintesi di peptidi e nella chimica organica. BOC-L-leucina è tipicamente un solido cristallino bianco o bianco sporco, ed è solubile in solventi organici come il diclorometano e il dimetilformamide, ma meno solubile in acqua. Il gruppo BOC serve a proteggere la funzionalità amminica durante le reazioni chimiche, consentendo modifiche selettive di altri gruppi funzionali. Dopo la deprotezione, BOC-L-leucina può partecipare a ulteriori reazioni per formare peptidi o altri derivati. La sua stabilità e reattività lo rendono un intermedio prezioso nella sintesi di prodotti farmaceutici e biochimici. Come molte sostanze chimiche, una corretta manipolazione e conservazione sono essenziali per mantenere la sua integrità e garantire la sicurezza negli ambienti di 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.
