MacroLig® Products

Chelation Chemicals

MacroLig® products consist of a range of specialty chemicals, including crown ethers, calixarenes, aza-crown ethers, cryptands, and tetraaza-crown ethers. Due to their unique properties, these products are used in a wide variety of laboratory and industrial scale applications in, for example, the research, chemical, medical, pharmaceutical, catalysis, and nuclear markets.

IBC has excellent synthesis capabilities for producing high-purity specialty chemicals for industry from gram to multi-ton scale. Many of these compounds have metal complexation properties. Specialty products and/or process-scale quantities are available after consultation with IBC personnel. All compounds are prepared to the highest quality standards, as determined by standard instrumental and elemental analyses. Prices and delivery times are available upon request.

IBC welcomes inquiries for joint applications development. One such example is the development and application of Bob Calix (MacroLig® 209) for the selective extraction of cesium from nuclear waste at the Savannah River site.
