Daclatasvir comprises a dihydropyrazine core fused to a tetrahydropyridine ring, with a sulfonamide group and aryl ether substitutions. The molecule features a triazole bridge connecting the pyrazine and pyridine moieties, enhancing conformational rigidity. As the parent drug, it retains full pharmacophoric integrity, enabling direct use in analytical workflows. This compound functions as an HPLC reference standard for quantifying antiviral APIs in quality control assays.
