Diclofenac Potassium
Diclofenac Potassium, with the chemical formula C14H13Cl2KO2, is a pharmaceutical-grade active ingredient used in oral and topical formulations for pain and inflammation management. It is supplied as a white to off-white crystalline powder, with a melting point between 150°C and 155°C, and is typically packaged in 25kg HDPE drums lined with food-grade polyethylene inner bags for moisture protection.
This compound is chemically distinct from diclofenac sodium, offering faster dissolution and absorption due to its potassium salt form, which enhances bioavailability in immediate-release formulations. Industry standards require a purity of at least 98.5% by HPLC, with limits on residual solvents and heavy metals as per ICH Q3C and Q3D guidelines. Typical impurities include diclofenac acid, dichlorophenylamine, and trace chlorinated byproducts, which must be controlled below 0.1% each.
Pharmaceutical manufacturers in Europe, Latin America, and Southeast Asia source this material for use in tablets, gels, and injectables targeting osteoarthritis, rheumatoid arthritis, and acute musculoskeletal pain. Buyers typically require batch-specific COAs, full analytical data, and GMP-compliant documentation. Packaging, storage, and transport conditions must maintain temperatures below 25°C and relative humidity under 60% to prevent degradation.

Sourcing Diclofenac Potassium from Zhangjiagang Clent Chemical Co., Ltd - China Import Guide
Before ordering, verify the supplier provides a Certificate of Analysis with HPLC purity, residual solvent limits, heavy metal content, and water content per batch. Confirm that the method used complies with USP or EP standards. Request a sample for independent testing if this is your first transaction. Do not accept generic statements without analytical data.
Confirm the Incoterms offered - typically FOB Shanghai or CIF destination - and ensure the supplier handles export documentation including commercial invoice, packing list, and bill of lading.
