Metal Scavengers: SiliaMetS®
Removing residual metals from post reactions can be a major issue. The toxic nature of transition metals has led to the reduction of tolerated residual concentration in active pharmaceutical ingredients (APIs) to single digit ppm. However, many important key steps, such as coupling reactions (Suzuki, Heck, Stille, Sonogashira…), Ring Closing Metathesis (RCM) and hydrogenation still require the use of metal catalysts.
Benefit from SiliCycle over 20 years know-how in metal scavenging, offering a wide range of ligands, available from lab scale to industrial scale.
