Since its inception in 1983, American Radiolabeled Chemicals, Inc. (ARC) has established itself as one of the leading suppliers of high quality radiolabeled and unlabeled chemicals in the world.  Our 2014 catalog contains more than 5,000 radiolabeled and unlabeled chemicals for life science research. More than 85% of the products in our catalog are exclusively available through ARC. Hopefully, with our wide selection of carbon-14 and tritium labeled products, one stop shopping will make it more convenient for you to order all your chemicals from ARC.

ARC also offers a wide range of custom synthesis services using Carbon-14 and Tritium. On a limited basis, ARC offers custom synthesis using 33P, 35S, 125I, and stable isotopes.

We have also began adding new products since our print version was published, that list can be found here.
