Applications
3,4-Difluoro-2-methoxyphenylacetic acid (CAS: 1558274-26-2) is a highly promising building block for drug molecules, primarily used in the field of innovative drug development.
NaV1.8 inhibitor (Suzetrigine/VX-548) intermediate: This is currently the most important application direction for this product. It is a key structural unit in the synthesis of novel non-opioid analgesics Suzetrigine (VX-548) and its derivatives, used to construct the phenylacetic acid side chain backbone in the molecule. Such drugs are attracting much attention in the field of pain management due to their non-addictive nature.
It is used to synthesize specific inhibitors of signaling pathways that inhibit the excessive proliferation of tumor cells and is an important raw material for constructing fluorinated anticancer drug molecules.
3,4-difluoro-2-methoxyphenyl group endows the molecule with unique electronic effects and metabolic stability, and is often used in structure-activity relationship studies during the lead optimization stage.
