Thiabendazole

Thiabendazole (CAS 148-79-8), commonly abbreviated as TBZ and approved as food additive E233, is a broad-spectrum antifungal agent used across food preservation, pharmaceutical manufacturing, and agricultural crop protection.

It controls mold, rot, and fungal pathogens at low effective concentrations, making it a practical active ingredient for both surface treatments and formulated products in various industrial sectors.

In post-harvest food handling, TBZ is applied as a surface treatment on citrus fruits, bananas, and potatoes to suppress mold and extend shelf life during storage and transit across global supply chains.

Pharmaceutical manufacturers use it as an active ingredient in anthelmintic formulations targeting parasitic worm infections in human and veterinary medicine, adhering to strict USP quality standards.

In agriculture, it functions as a systemic fungicide incorporated into seed treatments and turf management programs to protect against soil-borne and foliar fungal diseases throughout the growing season.

TBZ also serves as a catalyst precursor in certain polymerization and polymer stabilization processes, particularly in PVC production, where it enhances the durability and chemical resistance of the final material.

Thiabendazole is supplied as a white to off-white crystalline powder. It is available in food-grade, pharmaceutical, and technical grades to meet the distinct purity requirements of food and chemical processing.

Bulk supply is standard, with packaging options ranging from kilogram-scale to multi-tonne quantities depending on the specific grade and the logistical requirements of the purchasing organization.
