Grignard Pure Is Grounded In A Legacy Built On Chemistry Achievement And A Mission Built On Science And Engineering Innovation

Chemistry innovation is in our blood. Our ancestor, Victor Grignard, won the Nobel Prize in Chemistry for his pioneering breakthrough known to chemists around the world as “the Grignard reagent.” Grignard Pure continues its legacy of chemistry excellence and couples it with a mission to succeed and create a real, positive impact through science and engineering.

In addition to a staff informed by a commitment to purpose, passion for greatness, and unparalleled spirit of collaboration, Grignard Pure is also guided by the insights and counsel of a Science Advisory Team comprised of leading scientists, academics, and medical doctors from Rutgers University, The Johns Hopkins University, Harvard University, New York University, Oxford University (England.) and PUCRS (Brazil.) Together, this expanded team draws on the power of good in pursuit of creating transformative change.
