Phentolamine mesylate

Phentolamine Mesylate is a potent alpha-adrenergic antagonist. When sourcing, you must ensure the product meets USP (United States Pharmacopeia) or EP (European Pharmacopoeia) standards. Key specifications include a purity level (Assay) of 98.0% to 102.0% on a dried basis. You should verify the Loss on Drying (not more than 0.5%) and Residue on Ignition (not more than 0.1%). For injectable grades, bacterial endotoxin levels must be strictly controlled and documented.

Suppliers must provide a GMP (Good Manufacturing Practice) certificate to ensure the facility meets international health standards. Additionally, a Written Confirmation (WC) is required for export to the EU, and a Drug Master File (DMF) number is highly preferred for US-bound shipments. Always request a Certificate of Analysis (COA) for every specific batch and a Material Safety Data Sheet (MSDS) for handling protocols.

Phentolamine Mesylate is sensitive to light and moisture. It must be stored in tight, light-resistant containers. During the sourcing process, confirm that the supplier uses double-layer PE bags inside fiber drums or aluminum foil bags. The recommended storage temperature is usually controlled room temperature (20°C to 25°C), though some high-purity forms may require refrigeration (2°C to 8°C) to maintain long-term stability.

It is primarily sourced by pharmaceutical manufacturers for the production of injectable solutions used to prevent or control hypertensive episodes or for the reversal of soft-tissue anesthesia. It is also used in research and development for vasodilation studies. Buyers must ensure the grade (API vs. Research Grade) matches their specific manufacturing application.

As a pharmaceutical active ingredient, this product is subject to strict customs surveillance. You must ensure the supplier is registered with the relevant National Medical Products Administration and that you possess the necessary Import License for your specific country. Failure to provide correct HS Codes (typically 2933.29) or pharmaceutical permits can lead to seizure of goods at customs.

Utilize professional sourcing platforms like Made-in-China.com, which offer Audited Supplier reports. Before transferring large sums, conduct a third-party factory audit to verify the supplier's production capacity and QC lab equipment. Use Escrow services or Letters of Credit (L/C) for first-time high-value orders to mitigate financial risk.

Phentolamine Mesylate is often classified as non-hazardous for transport if pure, but this must be verified by a DGM report (Identification and Classification Report for Air Transport of Goods). For international shipping, Air Freight is recommended over Sea Freight to reduce transit time and exposure to fluctuating environmental conditions. Ensure the packaging includes desiccants and light-blocking layers.

Pricing for Phentolamine Mesylate is highly dependent on the purity grade and documentation (DMF vs. non-DMF). For bulk orders exceeding 10kg, you can typically negotiate a 10-20% discount. If you are a startup, look for suppliers on Made-in-China.com who offer small-scale R&D samples (10g-100g) before committing to a commercial-scale MOQ.
