New products in the new ARC catalog:

The new ARC catalog is now available for distribution! As you may already know, ARC has the biggest catalog of Radiolabeled compounds containing more than 5,000 different products, many of which are ARC Exclusives. Whereas other companies are downsizing their catalog listings, ARC continues to expand and offer more radiolabeled chemicals. This year ARC has added more than 200 new products again.

Former Sigma-Aldrich and GE (Amersham) customers are encouraged to contact us for their Radiochemical needs.

We want to assure the scientific community that ARC is hoping to secure enough Barium carbonate [14C] to be able to offer bulk intermediates as well as custom synthesis of complex molecules in the foreseeable future.

Radioactive isotopes
play an important role in the technologies that provide us with food, water and good health. Radioisotopes consist of unstable atoms with an unusual number of neutrons. This causes them to decay radioactivity, during which time they give off energy and subatomic particles. Radioisotopes do occur naturally, but are also artificially produced by bombarding particular elements with neutrons (usually emitted from a nuclear reactor). Radioisotopes are used in two major ways: for their chemical properties and as sources of radiation.

Radioisotopes are commonly used in bio-research. Biochemicals labeled with various radionuclides will function identically or similarly to the naturally occurring material.
Radioactive isotopes of familiar elements such as carbon can serve as tracers because they are chemically very similar to the non-radioactive isotopes, so most chemical, biological, and ecological processes treat them in an identical way. They can therefore be used as radiotracers, enabling researchers to follow that biochemical through a pathway or reaction of interest.

In medicine, radioisotopes are used for diagnosis and research. Radioactive chemical tracers emit gamma rays which provides diagnostic information about a person's anatomy and the functioning of specific organs. Radiotherapy also uses radiation in the treatment of some illnesses, such as cancer. More powerful gamma sources are used to sterilize syringes and other medical equipment. About one of every two people in Western countries are likely to experience the benefits of nuclear medicine in their lifetime.

In agriculture and animal husbandry, radioisotopes also play an important role. They are used to produce high intake of crops, disease and weather resistant varieties of crops, to study how fertilizers and insecticides work, and to improve the production and health of domestic animals.

Environmentally, radioisotopes are used to trace and analyse pollutants, to study the movement of surface water, and to measure water runoffs from rain and snow, as well as the flow rates of streams and rivers.

Scopus Research offers the scientific community a full range of top quality radiochemicals. The radiochemical and chemical purity of our products is assured to be 97% - 99%.

Important information
Licensing Requirements
Compliance with the terms of state, federal and institutional regulations for the procurement of radioactive materials is the responsibility of the user. Purchasers of radiolabeled compounds should familiarize themselves with all applicable regulations. To comply with current regulatory guidelines, Scopus Research must have a customer license or written certification stating that the customer is authorized to possess the type and quantity of radioactive material being ordered. This information must be provided before any order is shipped.

Narcotics and Dangerous Drugs
Narcotics and non-narcotics offered for sale on the website, in the catalog and in catalog quantities have been classified by the U.S. Drug Enforcement Administration (DEA) as exempt chemical preparations. They do not require a DEA license or DEA-222 form prior to shipment. Narcotics and psychotropic substances are regulated under the United National International Narcotics / Psychotropics Control Board. Customers of these products are responsible for their own applicable national rules and regulations. They should also inform us if their custom synthesis requests involve regulated substances.
