Acides carboxyliques
Les acides carboxyliques sont des molécules organiques caractérisées par un groupe fonctionnel de type carboxyle (-COOH). Ces acides sont fondamentaux dans diverses réactions chimiques, y compris l'estérification, l'amidation et la décarboxylation. Les acides carboxyliques sont largement utilisés dans la production de produits pharmaceutiques, de polymères et d'agrochimiques. Dans cette section, vous pouvez trouver un grand nombre d'acides carboxyliques prêts à l'emploi. Chez CymitQuimica, nous fournissons une large gamme d'acides carboxyliques de haute qualité pour soutenir vos applications de recherche et industrielles.
