A promising new Du Pont Development Chemical for your consideration
N-Phenylglycine with three distinct chemically reactive centers NHCH2C00CH3
NCH2C00
D u Pont N-Phenylglycine made its reputation as a dye intermediate. But its versatility is rapidly expanding its use in many different ways. Each of N-Phenylglycine's three active sites—a carboxyl group, a secondary amine group and the aromatic nucleus—will react separately. What's more, many unusual derivatives can be made from simultaneous or consecutive reactions involving two or more groups in combination. A few are shown above. So far, published literature indicates a n unusual variety of uses for " P G " and its derivatives. Herbicides, plant growth substances, polymerization promoters, stabilizers for alkaryl sulfonates and virus inhibitors are a few. " P G " has even been used as a component in plastics.
This is only a keyhole look at its potential. Maybe your research and development will open the door and expose a brand-new way to p u t N-Phenylglycine to work. We'll gladly send technical data and a sample. Just drop us a line on your company letterhead. E. I. du Pont de Nemours & C o .
