Sale price $128.00 Regular price

Fenbendazole capsules (444 mg) contain a high-purity antiparasitic benzimidazole compound widely used for experimental research applications. Manufactured in the USA under stringent quality control protocols, each batch undergoes rigorous third-party testing to verify purity (>99%) and consistency. Fenbendazole acts by selectively binding to β-tubulin in parasitic organisms, disrupting microtubule formation and cellular function.




Certificate Of Analysis


Frequently Asked Questions

What purity standard does Fenbendazole (444) meet?
Each batch is manufactured to a high-purity standard and independently verified by HPLC and LC-MS. Finished capsule formulations also undergo identity and quantity testing to confirm exact active mass per unit.
Why is raw purity testing different for capsules?
Finished formulations contain carriers, stabilizers, and excipients that interfere with raw purity assays. Capsules are tested for identity and quantity per unit, plus microbiological quality. Testing is matched to the format.
How should capsules be stored?
Store in the original sealed container at controlled room temperature, away from heat, moisture, and direct light. Retain the desiccant and keep the container closed. Do not refrigerate, as condensation can compromise capsule integrity.
Where can I find the certificate of analysis for this lot?
Every product links to its COA from the product page, and the full library is at the COA Reports page. Each certificate lists test methods, acceptance criteria, and results for that batch.
What does research use only mean for this order?
All Pure Bio Labs products are distributed strictly for laboratory research and in vitro experimentation. They are not approved for human or veterinary use.
