3]) and hydrazoic acid (formed when sodium azide contacts water) as the toxic agents in the iced tea.
Nearly 5 months after the restaurant incident, headspace gas chromatography/mass spectrometry analysis by the FBI laboratory detected hydrazoic acid, which is formed when sodium azide contacts water.
In that period reactions of isocyanides of particular importance were the formation of tetrazole derivatives from isocyanides and hydrazoic
acid developed by Oliveri-Mandala and Alagna in 1910 [15, see also 16] and the first three component reaction of the isocyanides (P-3CR) introduced by Passerini in 1921 [1, 9, 17, 18].
If sodium azide is released it can react with water to form hydrazoic
acid which is not only toxic but is highly explosive.
Immediately, the crystals transformed into the highly volatile hydrazoic acid, and the chemist inhaled just the barest whiff.
Betterton's studies have confirmed a widespread suspicion that once released from its cannister, hydrazoic acid breaks down in sunlight.
