Triphenylphosphine Oxide- Waste Not, Want Not

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,

Chromatographic Processes

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
