Tetramisole base

Tetramisole Base is a broad-spectrum anthelmintic agent primarily used in veterinary medicine to treat parasitic worm infestations. It functions by paralyzing the muscles of nematodes (roundworms) through the stimulation of their ganglia, leading to the expulsion of the parasite from the host. In industrial and laboratory settings, it serves as a key chemical intermediate for the synthesis of Levamisole, its levorotatory isomer, which is more biologically active.

Buyers should demand a purity level of ≥99% as verified by HPLC (High-Performance Liquid Chromatography). Key physical attributes include its appearance as a white to pale yellow crystalline powder with a specific melting point range (typically 87°C to 91°C). It is crucial to request a Certificate of Analysis (COA) for every batch to verify heavy metal limits, moisture content (loss on drying), and residue on ignition.

As a chemical substance, Tetramisole Base must be accompanied by a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) compliant with GHS standards. Suppliers should ideally hold ISO 9001:2015 for quality management and GMP (Good Manufacturing Practice) certification if the product is intended for pharmaceutical or veterinary applications. Ensure the product is registered under REACH for EU markets or complies with TSCA for the US.

Tetramisole Base is sensitive to light and moisture. It should be packaged in fiber drums with double-layer anti-static PE bags or aluminum foil vacuum packaging. Storage must be in a cool, dry, and well-ventilated warehouse (typically below 25°C), away from strong oxidizing agents and direct sunlight to prevent degradation or discoloration.

The primary risks include purity inconsistencies and regulatory seizures. To mitigate these, always request pre-shipment samples for third-party lab testing (e.g., SGS or Intertek). Furthermore, ensure the supplier provides a clear HS Code (typically 2934.99) to avoid customs classification errors that could lead to fines or delays.

Focus on long-term contract pricing rather than spot-market rates to hedge against raw material price volatility. Negotiate for staggered payment terms (e.g., 30% deposit, 70% against BL copy) and inquire about volume-based discounts—orders exceeding 500kg often qualify for a 10-15% price reduction. Always verify if the supplier is a 'Diamond Member' or 'Audited Supplier' on Made-in-China.com to ensure legitimacy.

Utilize Trade Assurance services provided by the platform to protect your payment until delivery is confirmed. Avoid using private bank accounts; all payments should be made to the company's official corporate account as listed on their verified profile. Ensure the Proforma Invoice (PI) explicitly states the purity, lead time, and compensation terms for sub-standard quality.

Since it is a chemical powder, it may be classified as 'sensitive goods' by some carriers. Use specialized chemical logistics providers who are experienced in handling DGM (Dangerous Goods Management) reports. For large volumes, Sea Freight (FCL/LCL) is most cost-effective, while Air Freight is suitable for urgent samples, provided the supplier provides a 'Certificate for Safe Transport of Chemical Goods'.
