The purchase of certain chemicals is regulated by the DEA under the Chemical Diversion and Trafficking Act (CDTA) since they can be used in the manufacturing of illicit drugs.  These listed chemicals are categorized in two lists for precursor reagents and solvents that can be used during the synthesis and purification of controlled substances.  Precursor chemicals include some common laboratory chemicals such as acetone, hydrochloric acid, sulfuric acid, and toluene. 

Unlike controlled substances, a DEA registration is not required to purchase DEA listed chemicals, but vendors may request additional information when ordering. Lab staff should complete the vendor supplied forms that are used to document the intended use. 

EHRS review/approval is not required for these chemical purchases.
