The expansion adds commercial specialty ligand, capacity manufacturing.
Johnson Matthey’s Catalysis and Chiral Technologies business unit is expanding its existing specialty ligand manufacturing capability to include commercial-scale manufacturing up to 100 kg. The expansion is largely focused on the Buchwald ligands from the Massachusetts Institute of Technology.
The Buchwald ligands are a class of bulky and electron-rich dialkylbiaryl monophosphine ligands, which are used for the in situ generation of active catalysts. These ligands are used for coupling reactions in the manufacture of both pharmaceuticals and specialty chemicals and are more commonly offered at a research scale for use in the laboratory, according to the company.
This is the third recent investment by the company, which has made investments at facilities in Taloja, India, last year and has further expansion underway in Royston, United Kingdom.
