Tetramisole hcl

Tetramisole Hcl is a potent anthelmintic agent. B2B buyers must ensure the product meets a purity level of ≥99% as confirmed by HPLC (High-Performance Liquid Chromatography). The appearance should be a white to pale yellow crystalline powder. It is critical to verify the melting point (typically 260-267°C) and ensure that heavy metal content is below 20ppm to meet pharmaceutical and veterinary grades.

Suppliers must provide a Certificate of Analysis (COA) for every batch. Depending on the target market, the product should align with BP (British Pharmacopoeia), USP (United States Pharmacopeia), or EP (European Pharmacopoeia) standards. For manufacturing reliability, prioritize suppliers with GMP (Good Manufacturing Practice) and ISO 9001:2015 certifications to ensure consistent quality control.

Tetramisole Hcl is primarily used as an anthelmintic (dewormer) in veterinary medicine for treating gastrointestinal nematodes in cattle, sheep, and swine. In laboratory settings, it serves as a levamisole precursor and an alkaline phosphatase inhibitor. Buyers should specify the intended use to the supplier to ensure the particle size (mesh) is optimized for their specific formulation, whether for oral drench, bolus, or injection.

The compound is sensitive to light and moisture. It must be stored in light-resistant, airtight containers at room temperature. Ensure the supplier uses double-layer PE bags inside fiber drums (25kg/drum) for bulk shipments. Buyers should request a shelf-life guarantee of at least 24 months from the date of manufacture.

The primary risks include purity degradation during transit and customs seizures due to improper labeling. To mitigate this, use third-party inspection services (like SGS or Intertek) to test samples before balance payment. Ensure the supplier provides a comprehensive MSDS (Material Safety Data Sheet) and follows GHS (Globally Harmonized System) labeling requirements to avoid delays at customs.

Always utilize secure payment terms such as Letter of Credit (L/C) for large volumes or Escrow-based services provided by reputable platforms like Made-in-China.com. Avoid direct wire transfers to private accounts. Verify the supplier's Business License and Export Permit for Precursor Chemicals (if applicable) to ensure they are a legitimate manufacturer rather than an unregulated middleman.

Tetramisole Hcl is generally classified as non-hazardous for transport, but this varies by jurisdiction. Confirm the HS Code (typically 293499) with your customs broker. For shipping to the US or EU, ensure the supplier is experienced with DDU/DDP terms if you lack an in-house logistics team. Request vacuum-sealed packaging to prevent moisture absorption during sea freight, which can cause clumping and reduce solubility.

Price in the chemical industry is highly dependent on raw material costs (intermediates) and order volume. Negotiate based on a tiered pricing model (e.g., 100kg vs. 1000kg). Ask for a 'Price Match' guarantee against current market indices and seek discounts for long-term supply contracts (Annual Purchase Agreements), which can reduce unit costs by 10-15% compared to spot market purchases.
