ABSTRACT
Can be detonated on impact, but is normally considered a stable intermediate (mp, 288°C), suitable for purification of pyridine.1 Occasionally explosions have occurred when the salt was disturbed,2 which have been variously attributed to the presence of ethyl perchlorate, ammonium perchlorate, or chlorates. A safer preparative modification has been described.3 It explodes on heating to above 335°C, or at a lower temperature if ammonium perchlorate is present.4
