Sigma-Aldrich is a leading life science and high technology company whose chemical products and services are used in scientific research, biotechnology, pharmaceutical development and as key components in high technology manufacturing. Sigma-Aldrich customers include more than a million scientists and technologists in life science companies, universities and government institutions, hospitals and industry. The Company operates in more than 50 countries and has over 20,000 employees with the objective to provide excellent services worldwide.

Sigma-Aldrich is a large international conglomerate and is orientated to B2B (business to business) interactions. The company focuses on a large spectrum of different substances rather than just one specific product. Generally you can’t buy Fenbendazole directly from the company’s website, is some countries you can, such as US. If you send them an inquiry, you get redirected to a local representative. Not all local representatives sell chemicals to private customers, and even if they do, you have to wait a couple of weeks or even months for the local Sigma-Aldrich representative to receive Fenbendazole and get a deal for you. That makes Sigma-Aldrich very different from other reviewed suppliers.


In the conducted study, the company’s Fenbendazole, which is made in Germany, proved to be very good quality, they took the second place for the highest purity of the tested suppliers. The company claims that their product is 98% pure, in our test it proved to be 99.93% pure. Reason for this might be that the 2% impurity was ethanol, which evaporated, or the specific batch was of better quality.

In conclusion, Sigma-Aldrich provides excellent quality Fenbendazole, but it will take a long time to acquire their product and it will cost significantly more compared to other suppliers.


The company offers Fenbendazole only in powder form and only in two packages – 5g and 100g. The prices are more than twice expensive compared to the other suppliers.


MERCK does not offer these items directly to customers. Products are marketed to distributors such as veterinary clinics, pharmacies, and different stores, who subsequently sell to customers. These items can generally be found everywhere in the globe.


Since Panacur C and Safe-guard are official certified veterinary brands, which means they are GMP licensed, the quality is rigorously checked and accounted for. This also implies that the price may be greater for a relatively tiny size of the item and product availability may be challenging at times. Nonetheless, their merchandise quality is time-tested and reliable.

The purity of the product has not been analysed since all their Fenbendazole preparations include fillers, making the product unsuitable for a purity comparison.


Although expensive, Panacur C and Safe-guard are safe Fenbendazole options. In addition, Panacur C is designed specifically for animals and includes ingredients that make it appealing to them and easy for them to digest.
