Essential components in accessing active pharmaceutical ingredients (API), catalysts are compounds that aid in the formation of chemicals without getting consumed in the process. Developed to reduce waste, environmental footprint and cost, they play an important role in the 12 principles of green chemistry.

J&K Scientific offers an extensive range of metal catalysts and organocatalysts for research and manufacturing.
