Global. Responsive.

We have expanded production to Europe with a 4,600-square-meter manufacturing site in Kościan, Poland. The facility is designed to meet stringent quality standards such as FSSC 22000 certification and also features many sustainability initiatives.


Product Highlights:

  • Pharma Pure: We offer high purity chemical salts for both upstream and down stream processes in the biopharmaceutical industry. Our Jost Pharma Pure line is high purity, multi-compendial and endotoxin tested.


  • Permeation Enhancers: Intestinal permeation enhancers are excipients included in formulations to improve the absorption of an API by enhancing membrane permeation. Jost Chemical offers high purity, compressible Sodium Caprate and Sodium Caprylate as permeation enhancers of oral delivery systems for therapeutic drugs with poor bioavailability, such as Insulin.


  • Closer to Zero: Jost Chemical now has the capability to test to even lower levels of impurities. As customer requirements for trace metals are increasingly lower, Jost Chemical is prepared to meet these detection requirements. Inductively coupled plasma–mass spectroscopy (ICP-MS) is often the instrument of choice for routine applications requiring ultratrace detection limits. For a number of elements, spectroscopic interferences can have a significant impact on the ability to achieve low detection limits by traditional ICP-MS systems. Jost recently acquired a state-of-the-art NexION 5000 ICP-MS. This system can quantitatively detect heavy metals and other analytes down to single digit parts per billion (<0.01 ppm).


Purity. Traceability. Trust.

We offer a short supply chain—we manufacture and test everything that we sell. We specialize in ultra high purity chemical salts with exceptionally low levels of elemental impurities.

Jost’s high-purity chemical salts meet USP, EP, ACS, and FCC monographs, are lot-to-lot consistent, and have extremely low levels of lead, arsenic, cadmium, mercury, aluminum, etc. Our wide selection of 250+ free-flowing chemical salts includes Ammonium Sulfate, Potassium Phosphate, Sodium Acetate, Sodium Carbonate, Sodium Phosphate, and Sodium Sulfate.

Jost Chemical products’ applications in the pharmaceutical and biopharmaceutical markets include API synthesis, as pH buffers for fermentation, as process intermediates, and in cell culture media and protein synthesis.

For 35 years, Jost Chemical has manufactured high-purity chemical salts for the pharmaceutical, biopharmaceutical, and nutritional markets. Our FDA-registered manufacturing site operates under bulk pharmaceutical cGMP. As a trusted, global supplier, Jost manufactures every high purity chemical salt we sell and our pharmaceutical grade products assist customers to meet ICH Q3D Elemental Impurity Guidelines and USP regulations per <232> and <233>. They are BSE/TSE free, GMO free, allergen free, and Kosher and Halal certified.
