Trans World Chemicals, Inc. was incorporated in 1974 by a group of PhD chemists who envisioned a company that would supply researchers with a unique line of chemical products not offered by the large chemical supply houses. Over the years, our customer base has grown to include people engaged in all areas of biomedical, pharmaceutical and agricultural research as well as universities and other chemical companies.
