Application

This sulfonyl chloride derivative serves as a key intermediate in medicinal chemistry for the preparation of sulfonamide-containing bioactive compounds. Researchers utilize it in Suzuki-Miyaura cross-coupling reactions to create novel triazolopyrimidine scaffolds with potential kinase inhibitory properties. The reactive sulfonyl chloride group enables efficient conjugation with amines and alcohols to generate diverse sulfonamide and sulfonate esters for biological evaluation. It has shown particular utility in developing antimalarial and antibacterial agents targeting folate biosynthesis pathways.
