Description

5-Hydroxy Thiabendazole is a key metabolite and derivative of the broad-spectrum anthelmintic and fungicide, thiabendazole. This compound matters as a crucial analytical reference standard and a potential intermediate in the synthesis of advanced pharmaceutical and agrochemical products. It is primarily needed by research institutions, analytical laboratories, and manufacturers in the pharmaceutical and agrochemical sectors for quality control, method development, and novel compound synthesis.

Application

• Primary use as an analytical reference standard for HPLC, LC-MS, and other chromatographic methods in pharmaceutical quality control.
• Critical metabolite standard in pharmacokinetic and metabolic studies of thiabendazole in veterinary and human medicine.
• Key chemical intermediate for the research and development of novel benzimidazole-class fungicides and anthelmintics.
• Used in environmental analysis to detect and quantify thiabendazole residues and their degradation products in soil and water.
• Employed in food safety testing to monitor for pesticide residues and ensure regulatory compliance.
• Valuable building block in academic and industrial research exploring structure-activity relationships within the benzimidazole family.
