Grignard reagents

One of the world’s largest producers of custom chemicals, WeylChem US, offers the proper technical packages and production systems to reliably supply manufacturers with Grignard reagents and Grignard-derived intermediates anywhere in the world.

About our Grignard Technology

What began in the 1970’s as a strategy to produce flavorings synthetically using common Grignard reagents has expanded into industrial scale production for the manufacturing industries of the world. Today we offer commercial Grignard reagents, niche Grignard reagents, and Grignard-derived intermediates from pilot to industrial scale. If you plan to reconfigure your plant for new projects or adopt chemistries and processes that change the economics of your in-house Grignard manufacturing capability, consider the manufacturing assets, laboratory services, and decades of expertise offered by WeylChem US.

DownStream Chemistry "n+x advantage™"

With multipurpose facilities, WeylChem US is equipped to supply a wide range of multi-step chemical reactions that involve Grignard reactions. Offering commercial Grignard reagent chemistry as well as downstream chemistry, WeylChem tailors manufacturing to deliver on the promise of higher performance and value.

Packaging & Solvent Options

At WeylChem US, there is currently a limited number of cylinders in our fleet. We understand that it is very important to some of our customers to have material packaged in cylinders, and we therefore try to accommodate as many orders as possible in this packaging. Please note that cylinder packaging comes on a first come, first serve basis, or we are happy to extend our cylinder fleet at a lead time and a cost. For more information regarding your inquiries, please contact Erika Moseley at Erika.Moseley@Weylchem.com
