Zhonghan Biotech's Abemaciclib Intermediates: High-Quality Key Intermediates Empowering Efficient Synthesis of CDK4/6 Inhibitors

As an orally highly selective CDK4/6 inhibitor [https://www.xsu.com/n-isopropylacetamide-cas-1118-69-0-product/], Abemaciclib is a core targeted drug for the treatment of HR+/HER2- breast cancer, widely used in the clinical treatment of locally advanced and metastatic breast cancer. Its synthesis chain has stringent requirements for the purity, stability and batch consistency of key intermediates, which directly determine the quality of active pharmaceutical ingredients (APIs) and the safety of preparations.

Jinan Zhonghan Chemical Technology Co., Ltd. focuses on the R&D and large-scale production of high-end pharmaceutical intermediates. Relying on mature processes, strict quality control and customized production capacity, we have launched a series of high-purity key intermediates for Abemaciclib, covering key nodes of core skeleton construction and side chain synthesis, providing pharmaceutical enterprises with stable, compliant and cost-effective raw material support
