Description

Tetramisole Hydrochloride is a high-purity, small-molecule organic compound widely recognized for its potent anthelmintic and immunomodulatory properties. Its primary commercial value lies in its role as a key intermediate in the synthesis of Levamisole, a critical active pharmaceutical ingredient (API) used in both human and veterinary medicine. This product is essential for manufacturers in the pharmaceutical, veterinary, and fine chemical sectors requiring a reliable, high-quality building block for therapeutic applications.

Application

• Pharmaceutical Intermediate: Primary use as a precursor in the synthesis of the API Levamisole hydrochloride.
• Veterinary Anthelmintic: Used in the production of deworming medications for livestock and companion animals.
• Immunomodulatory Research: Serves as a research chemical in immunological studies and drug discovery.
• Fine Chemical Synthesis: Acts as a chiral building block for more complex organic molecules in specialty chemistry.
• Reference Standard: Utilized as an analytical standard in quality control laboratories for method development and validation.

Quality Control

Our Tetramisole Hydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to ensure it meets stringent specifications suitable for pharmaceutical intermediate use. A Certificate of Analysis (COA) detailing purity, identity, and related substances is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
