API Intermediates
Our API Intermediates category includes a full range of high-purity upstream synthetic precursors for mainstream innovative drugs and generic pharmaceutical APIs, covering multiple high-growth pharmaceutical fields such as analgesia and anti-inflammation, cardiovascular anticoagulation, male functional drugs and chronic disease treatment. Representative products include Loxoprofen sodium precursor intermediates, Apixaban cardiovascular intermediates, and core fragments of PDE5 inhibitor drugs. All API intermediates adopt low-impurity synthetic processes, featuring high finished product purity, low single impurity content, stable batch repeatability and controllable residual substances, fully meeting the strict incoming inspection standards of pharmaceutical factories and industrial synthesis requirements. These intermediates are widely used in new drug molecular research, generic drug process optimization and large-scale commercial API production. In accordance with international trade compliance rules, all regulated API supporting intermediates will be reviewed for customer enterprise qualifications before quotation and delivery to ensure standardized and compliant export transactions.
