Sulfonates et Sulfates Organiques
Les sulfonates sont des composés contenant un groupe fonctionnel -SO₃, où un atome de soufre est lié à trois atomes d'oxygène, dont l'un est attaché à un groupe alkyle ou aryle. Ces composés sont utilisés dans la formulation des API en raison de leur capacité à améliorer la solubilité et la stabilité des principes actifs. Leur structure peut également conférer des propriétés antimicrobiennes ou anti-inflammatoires.
Les sulfates organiques sont des dérivés de l’acide sulfurique, où le groupe -OSO₃ est lié à un atome de carbone dans une structure organique. Ils sont employés dans la fabrication de certains API pour modifier la solubilité et la bioactivité des composés. Les sulfates sont également utiles pour améliorer la biodisponibilité de certains principes actifs dans les traitements pharmaceutiques.
Chez CymitQuimica, nous proposons des sulfonates et des sulfates organiques de haute pureté pour une utilisation dans les formulations pharmaceutiques, la chimie fine et la biotechnologie.
