Gruppi protettivi
I gruppi protettivi sono utilizzati nella sintesi organica per mascherare temporaneamente gruppi funzionali reattivi, consentendo reazioni selettive senza interferenze. Questi gruppi sono essenziali nei processi di sintesi multi-step, assicurando che parti specifiche della molecola rimangano non reattive mentre vengono eseguite altre reazioni. In questa sezione troverai una varietà di gruppi protettivi adatti a diversi gruppi funzionali, insieme a reagenti per la loro introduzione e rimozione. Presso CymitQuimica, offriamo una gamma completa di gruppi protettivi di alta qualità per facilitare le tue strategie sintetiche.
