Take the easy route to new product development Whether you're developing a new pharmaceutical or agricultural chemical, or looking for an easier route to an existing product, head straight for Eastman· p-benzoquinone or TECQUINOL· hydroquinone. Both of these Eastman intermediated are highly reactive, versatile and can be conveniently annulated to produce budding blocks for more complex structures. Because hydroquinone readHy undergoes electrophiHc substitutions such as the Marmich and Friedel Crafts reactions, it Just might elmtnate several steps of a synthesis. One enterprising chemist used it as an Intermediate in the

preparation of liquid crystal polymers. A real shortcut. Eastman p-benzoquinone is highly electrophilic and can be reacted with a variety of nucteophRes to form tri- and tetra-f unctional aromatic compounds. And it provides a quick, easy route to dihydroxybenzoquinone. For your free sample of TECQUINOL hydro quinone or Eastman p-benzoquinone, along with one of the most complete literature searches available, write on your company letterhead to Eastman Chemical Products, Inc., a subsidiary of Eastman Kodak Company, Industrial Chemicals Division, Kingsport, Tennessee 37662.
