Love it or hate it, triphenylphosphine oxide (TPPO, Figure 1) is something we all encounter at some point during our chemistry careers. Most of the time it’s just a by-product from well-established and widely used process such as the Mitsunobou, Wittig, Staudinger, Appel and Corey-Fuchs reactions.1 I remember having a vial full of the white,

Preparative chromatography is a versatile purification technique used in various industrial sectors including petrochemistry, sugar production, pharmaceutical and fine chemistry, to name only a few. While this technology is often considered complex, expensive and sometimes not scaleable, industrial success stories prove the opposite. In our recent webinar, Dr. Pfister from Ypso-Facto presented a reliable approach
