About Us

Trans World Chemicals began in 1974 with 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.

In 2016, Trans World Chemicals was purchased by two scientists with 20-years' experience each formerly with the Aldrich Chemical Company, Scott Batcheller, Ph.D. and Robert Todd Ph.D., operating as A-Chem LLC. The company relocated to Milwaukee, Wisconsin, where we can build our product offer, operations, and customer service. We now bring together the core chemistry expertise of Trans World product lines with extensive and unique expertise in catalysts, ligands, organometallics, and highly air-sensitive chemicals.

We manufacture over 98% of everything we sell, this together with our very low cost structure puts us in an excellent position to offer the lowest price possible.

We maintain a large inventory with over 95% of our entire catalog in stock and ready to ship. We offer custom synthesis as well as bulk manufacturing. Our catalog is periodically updated with new products and we are often the sole supplier of a particular product you will find when searching any of the available chemical directories.

Our offices and laboratories are located in Milwaukee, Wisconsin. Please feel free to call or write to us with your comments, questions or suggestions.
