Arbidol synthesis is a multi-step process that demands precise control at each stage. As a key antiviral API, Arbidol requires high-purity intermediates to achieve the ≥98% overall purity standard required for pharmaceutical use. The synthetic route to Arbidol typically begins with inexpensive ethyl acetoacetate as the starting material and proceeds through Nenitzescu reaction, acylation, bromination, thiophenolisation, Mannich reaction, and salt formation. Each Arbidol intermediate in our portfolio is characterized with HPLC purity verification, NMR identity confirmation, and residual solvent analysis to ensure seamless progression through the synthetic cascade. Cosperpharm's Arbidol intermediates are designed to support both laboratory-scale R&D and commercial manufacturing campaigns.
