Nitrogen mustards (HN-1, HN-2, HN-3) are blister agents that are colorless to yellow, oily liquids that evaporate very slowly. HN-1 has a faint, fishy or musty odor. HN-2 has a soapy odor at low concentrations and a fruity odor at higher concentrations. HN-3 may smell like butter almond.
Although nitrogen mustards could be used in chemical warfare, there are presently no records of such use. HN-1 has been used to remove warts in the past, and HN-2 has been used sparingly in
chemotherapy.
It is unlikely that the general public will be exposed to nitrogen mustards agents HN-1, HN-2, and HN-3. Exposure to vapors of nitrogen mustards can damage the
respiratory airways. Contact with the skin or eyes may cause
burns. When nitrogen mustards are absorbed by the body, they may cause damage to
bone marrow and the
immune system. Exposure to high levels can cause
death. Nitrogen mustards HN-1, HN-2, and HN-3 have not been identified in any of the 1,585 National Priorities List
sites identified by the
Environmental Protection Agency (EPA).
