n-Propyl Bromide (nPB)

N-Propyl bromide (nPB) or 1-bromopropane, is a 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).

N-Propyl bromide is designated as a Higher Hazard Substance under TURA, which lowers the reporting threshold to 1,000 lb/year, effective January 2016.
