About Prima Chemicals | Chemical Manufacturing Company Prima Chemicals, located in Ahmedabad, Gujarat, India was founded in 1976 for manufacturing Pyrazolones, which are used as intermediates for Pigments, Acid dyes and Solvent Dyes. What began as a small unit is now the single largest manufacturer of Pyrazolones derivatives in the world. Our strength is our knowledge, hard work and humble beginnings and hence, we always opt for niche segments where technical expertise and active management involvement is needed to carry out the production. Based on this trend, we have diversified into a wide range of products having equally diverse applications. Prima group now has 6 manufacturing units spread over three group companies.
