Eliminate batch failures caused by adventitious water. With a strong background in manufacturing and handling Grignard reagents, MPSV Labs manufactures and refines standardized anhydrous ethers, aromatics, chlorinated organics, and sterically hindered alcohols under the PreSynth line with Karl Fischer moisture strictly controlled below 500 ppm (and further down tailored for sensitive organometallic workflows).
