Pyrrolidine

Pyrrolidine is a versatile heterocyclic intermediate primarily used in the synthesis of pharmaceuticals (such as levetiracetam and piracetam), agrochemicals, and rubber accelerators. It also serves as a building block in organic synthesis for creating fine chemicals and as a catalyst in certain chemical reactions. In the electronics industry, it may be used in specialized cleaning agents or as a precursor for photoresist components.

For most industrial applications, a purity level of ≥99.0% is standard. Buyers should request a Certificate of Analysis (COA) to verify levels of moisture (typically ≤0.2%) and specific impurities. The appearance should be a clear, colorless to pale yellow liquid. Ensure the supplier provides Gas Chromatography (GC) reports to confirm the chemical composition meets your specific manufacturing requirements.

Pyrrolidine is classified as a flammable and corrosive liquid (UN 1922, Class 3, Packing Group II). Suppliers must provide a comprehensive Safety Data Sheet (SDS/MSDS) compliant with GHS standards. Ensure the product meets REACH registration requirements if exporting to Europe, and verify that the manufacturer adheres to ISO 9001 for quality management and ISO 14001 for environmental safety.

Due to its hygroscopic nature and flammability, Pyrrolidine should be stored in cool, dry, well-ventilated areas away from heat sources and oxidizers. Standard packaging includes 170kg or 200kg galvanized iron drums or IBC tanks. It is crucial to ensure the containers are nitrogen-blanketed to prevent oxidation and moisture absorption, which can degrade the chemical's quality over time.

As a Dangerous Good (DG), the primary risk involves logistical delays due to strict maritime and customs regulations. Buyers must ensure the supplier has a Dangerous Goods Export License and uses certified DG packaging. Incorrect labeling can lead to seizure by customs or heavy fines. It is highly recommended to use freight forwarders who specialize in Class 3/8 hazardous chemicals.

When sourcing via Made-in-China.com, prioritize Audited Suppliers who have undergone on-site verification. Use Secured Payment services to protect your funds until shipping documents are verified. For large-scale orders, consider appointing a third-party inspector (like SGS or Intertek) to conduct pre-shipment sampling and loading supervision to ensure the volume and quality match the contract.

Chemical prices are often tied to raw material costs (like 1,4-butanediol) and global oil prices. Negotiate based on volume-based pricing tiers; typically, purchasing in full container loads (FCL) can reduce unit costs by 10-15% compared to LCL. Discuss long-term supply contracts to hedge against price volatility and ensure a stable supply chain during peak demand periods.

Buyers must confirm the HS Code (typically 293399) and check for any anti-dumping duties or specific import permits required by their local government. Ensure all documentation, including the Commercial Invoice, Packing List, COA, and Dangerous Goods Declaration, is perfectly aligned to avoid demurrage charges at the port of destination.
