Esters et Dérivés
Les esters sont des composés organiques formés par la réaction d’un acide (généralement un acide carboxylique) avec un alcool, libérant de l’eau au cours du processus. Leur structure chimique comprend un groupe fonctionnel -COO-, où un atome de carbone est lié à un groupe oxygène et à un groupe alkyle ou aryle. Les esters ont une large gamme d’applications dans l’industrie, notamment en tant que solvants, parfums, arômes et produits pharmaceutiques. En pharmacologie, certains esters sont utilisés comme promédicaments, car leur structure permet une libération contrôlée ou une biodisponibilité accrue des principes actifs.
Chez CymitQuimica, nous proposons des esters et leurs dérivés pour la recherche en chimie organique, la formulation de médicaments et les applications industrielles.
