Regorafenib manufacturers

When sourcing Regorafenib as an Active Pharmaceutical Ingredient (API), buyers must prioritize purity levels of ≥99% as determined by HPLC analysis. It is essential to verify the molecular formula (C21H15ClF4N4O3) and ensure the product meets USP or EP compendial standards. Suppliers should provide a detailed Certificate of Analysis (CoA) covering heavy metals, residual solvents, and related substances to ensure clinical or research efficacy.

Due to its nature as a potent multi-kinase inhibitor, procurement requires strict documentation. Buyers must ensure the manufacturer holds a GMP (Good Manufacturing Practice) certification. For entry into regulated markets, a DMF (Drug Master File) or CEP (Certificate of Suitability) is highly preferred. Additionally, a valid MSDS (Material Safety Data Sheet) is required to manage handling risks and environmental safety.

Regorafenib is sensitive to environmental factors. Suppliers must demonstrate that the product is stored at 2°C to 8°C (refrigerated) or as specified by stability testing data to prevent degradation. Ensure the packaging uses amber glass vials or high-density polyethylene (HDPE) containers with moisture-proof sealing to maintain chemical integrity during long-term storage and transit.

Regorafenib is primarily sourced for pharmaceutical manufacturing of finished dosage forms (tablets) or for oncology research and development. It is widely utilized in the treatment of metastatic colorectal cancer (mCRC), gastrointestinal stromal tumors (GIST), and hepatocellular carcinoma (HCC). B2B buyers must ensure the grade (Research Grade vs. Pharma Grade) aligns with their specific end-use application.

The primary risks include customs seizure due to lack of proper medical import licenses and quality inconsistency between sample and bulk batches. To mitigate this, use third-party testing services (like SGS or Intertek) to verify the chemical composition before final payment. Always confirm the Harmonized System (HS) Code (typically 2933.39) to ensure correct tariff application and avoid legal delays.

Utilize secure payment terms such as Letters of Credit (L/C) or platforms that offer Trade Assurance to protect your funds until delivery is confirmed. On Made-in-China.com, prioritize Audited Suppliers who have undergone on-site verification of their production facilities and business licenses to reduce the risk of fraud.

Given its high value and sensitivity, use cold-chain logistics with temperature data loggers included in the shipment. Select reputable couriers experienced in handling dangerous goods (DG) if the concentration requires it. Ensure all export permits from the country of origin and import permits for the destination country are synchronized to prevent port storage fees.

Focus on long-term supply stability rather than just the lowest price. Negotiate for tiered pricing based on annual volume commitments, which can yield 10-20% discounts. Request a Quality Agreement that defines liability in case of batch failure, and ensure the supplier can provide stability data updates throughout the contract period.
