Chemical Manufacturing Company, Organic, Bulk Chemical Suppliers

About Us

Trans World Chemicals began in 1974 with a group of Ph.D. 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 Scott Batcheller, Ph.D., and Robert Todd, Ph.D., career chemists and former colleagues from the Aldrich Chemical Company — each bringing more than two decades of industry experience to the enterprise and an ambition to enhance the core chemistry expertise of Trans World product lines with a unique expertise in catalysts, ligands, organometallics, and highly air-sensitive chemicals.

Continuing operations as a division of Wisconsin-based A-Chem, LLC, we relocated to Milwaukee, Wisconsin, and spent the ensuing years building our product offer and operational capacity, while maintaining a focus on serving our customers. In 2022, we expanded into our present office and laboratory facility in Menomonee Falls, Wisconsin.

Manufacturing over 98% of everything we sell and operating under a very low cost structure puts us in an excellent position to offer the lowest prices possible.

We maintain a large inventory, with over 95% of our entire catalog in stock and ready to ship, and offer custom synthesis as well as bulk manufacturing services. Our catalog is periodically updated with new products, and we are often the sole supplier of particular products listed across available chemical directories.

Please feel free to call or write to us with any comments, questions, or product inquiries.
