Cantharidin

Cantharidin is a potent vesicant primarily utilized in the pharmaceutical industry for the treatment of specific dermatological conditions, such as molluscum contagiosum and common warts. In a laboratory setting, it is used as a biochemical tool for studying protein phosphatase inhibition (specifically PP1 and PP2A). B2B buyers must ensure the product is sourced for legitimate medical or research purposes only.

For pharmaceutical applications, buyers typically require a purity of ≥98% or 99% (HPLC). It is essential to request a Certificate of Analysis (COA) that details the melting point, moisture content, and heavy metal limits. The substance should be handled as a highly toxic compound, requiring suppliers to provide a comprehensive Safety Data Sheet (SDS) outlining proper storage and handling protocols.

Due to its high toxicity, Cantharidin is strictly regulated. Suppliers must comply with local and international chemical safety regulations. Buyers should verify that the manufacturer holds ISO 9001 for quality management and, if intended for clinical use, adheres to GMP (Good Manufacturing Practices). Ensure the product is labeled according to the Globally Harmonized System (GHS) for hazardous substances.

Cantharidin is classified as a dangerous good for transport. It must be shipped via specialized hazardous material carriers that comply with IATA (air) or IMDG (sea) regulations. Ensure the packaging is UN-certified to prevent leakage, and always confirm that the freight forwarder is experienced in handling Class 6.1 toxic substances.

Prioritize Audited Suppliers on Made-in-China.com who have undergone third-party verification by organizations like SGS or TÜV Rheinland. Request business licenses and specific chemical production permits. Engaging in a video factory audit to inspect their laboratory capabilities and safety infrastructure is highly recommended before placing high-value orders.

Utilize secure payment methods such as Letters of Credit (L/C) or trade assurance services provided by the platform to protect your capital. Clearly define quality inspection terms in the contract, stating that final payment is contingent upon the results of an independent third-party lab test (e.g., Intertek or Pony Testing) to ensure the chemical composition matches the agreed specifications.
