DPC and BPD are used as building blocks for a number of commercial and developmental catalysts for the preparation of chiral and achiral products.
Novolyte's phosphinic acid compounds, particularly benzene phosphinic acid, are used as catalysts and stabilizers in the production of nylon 6,6 polymer for fiber applications, including air bags and tire chord.
