n-Propyl bromide

This fact sheet is part of a series of chemical fact sheets developed by TURI to help Massachusetts companies, community organizations and residents understand the chemical's use and health and environmental effects, as well as the availability of safer alternatives. Since Massachusetts companies report usage under the Toxics Use Reduction Act, readers will learn how the chemicals are being used and by which companies. 

N-Propyl bromide (nPB) or 1-bromopropane, is a relatively new solvent that is used in vapor degreasing, metal cleaning, and dry cleaning; as a solvent carrier in adhesives; and as a chemical intermediate. The US Environmental Protection Agency (EPA) classifies nPB as a volatile organic compound (VOC).

Use of nPB is increasing as an alternative for other solvents that have become more strictly regulated, such as methylene chloride, perchloroethylene (perc), and trichloroethylene (TCE). This trend is of concern because evidence has emerged linking nPB to a range of human health hazards. In 2009, nPB was added to the list of Toxic or Hazardous Substances subject to regulations under the Massachusetts Toxics Use Reduction Act (TURA).

 nPB is relatively new on the market and has received minimal regulatory attention to date.
