Stable Isotopes

Custom Synthesis

ISOTEC has the most experienced team of stable isotope custom synthesis chemists in the industry, led by impressive group of Ph.D.'s, each one an expert in his field. ISOTEC routinely engages in the multiple step syntheses of complex labeled molecules including, metabolites and steroids. On-site production capabilities and an inventory of basic starting materials enable us to provide rapid synthesis of new compounds. We can deliver your custom synthesis compound faster than any other company in our industry.

We will synthesize quantities ranging from milligrams to kilograms, provide custom packaging services, and guarantee client confidentiality.
