Amino-4-pyridine price

For industrial and pharmaceutical applications, 4-Aminopyridine (CAS No. 504-24-5) must typically meet a purity level of ≥99%. Buyers should verify the melting point (157-160°C) and ensure the product is a white to off-white crystalline powder. Request a Certificate of Analysis (COA) for every batch to confirm moisture content and heavy metal limits are within acceptable ranges.

4-Aminopyridine is a potent potassium channel blocker. It is primarily used as a chemical intermediate in the synthesis of pharmaceuticals and as an avicide in agricultural settings. Due to its high toxicity, it requires specialized handling protocols and must be stored in a cool, dry, and well-ventilated area away from incompatible substances like strong oxidizing agents.

Suppliers must provide a Material Safety Data Sheet (MSDS/SDS) compliant with GHS standards. Since it is a hazardous chemical, ensure the manufacturer holds an ISO 9001 quality management certification and, if intended for pharma use, adheres to GMP (Good Manufacturing Practice). Verify that the supplier is registered under REACH if exporting to the EU, or complies with TSCA for the US market.

Price is heavily influenced by raw material costs (pyridine) and environmental regulation enforcement in manufacturing hubs. To optimize costs, consider bulk procurement (25kg drums or larger) which can reduce unit prices by 15-20%. Always factor in the Total Cost of Ownership (TCO), including specialized hazardous material (HazMat) shipping fees and customs duties.

4-Aminopyridine is classified as a Class 6.1 Toxic Substance. It must be shipped according to IMDG (sea) or IATA (air) dangerous goods regulations. Ensure the packaging is UN-certified (typically fiber drums with inner plastic lining) to prevent leakage. Failure to declare hazardous goods correctly can lead to heavy fines or seizure by customs.

Use secure payment methods and prioritize suppliers on Made-in-China.com who have undergone on-site audits. It is highly recommended to use third-party inspection services (like SGS or Intertek) to perform pre-shipment sampling and testing to ensure the chemical composition matches the agreed specifications before final payment.

Focus on long-term supply stability rather than just the lowest price. Negotiate for staggered delivery schedules to manage inventory and request price protection clauses against market volatility. Ask for a sample (10-50g) for lab testing before committing to a full-scale commercial order.

Check the Harmonized System (HS) Code (typically 293339) for specific import tariffs in your country. Be aware of dual-use chemical regulations; some jurisdictions require an Import License or an End-User Certificate (EUC) to ensure the product is not diverted for prohibited uses. Always consult with a licensed customs broker experienced in chemical imports.
