An AstraZeneca Case Study
> back to SiliaMetS Case Studies
In 2008, AstraZeneca published a paper in witch they removed palladium impurities in a large-scale process. The workup method that was found to work the best was a treatment with SiliaMetS Thiol (25 % w/w or ~1.4 kg) at 50°C to purify more than 6.7 kg. Final residual palladium concentration was as low as 1-2 ppm
