(2R,3R)-3-(2,5-Difluorophenyl)-3-Hydroxy-2-Methyl-4-(1H-1,2,4-Triazol-1-Yl)Thiobutyramide Sulfate is a specialty chemical intermediate used in the synthesis of triazole-based antifungal agents. Its structure, featuring a 1,2,4-triazole ring and difluorophenyl group, is crucial for developing drugs that inhibit ergosterol biosynthesis in fungi, disrupting cell membrane integrity. This intermediate supports the production of pharmaceuticals effective against pathogens like Candida and Aspergillus, particularly for systemic infections in immunocompromised patients. The sulfate salt enhances solubility and stability in synthetic processes.
