Mutagenicity of Alkyl Azides.

Biological and Pharmaceutical Bulletin, 1995
Alkyl azides showed mutagenicity for S. typhimurium TA100 strain with S9 mix. However, no significant activity was observed for TA98 either with or without S9 mix or for TA100 without S9 mix. On the other hand, 3-azido-1,2-propanediol showed the enantioselective activity regardless of S9 mix.
