Solutions containing 1000 mg kg - 1 of allyl isothiocyanate (AITC) in buffers of pH 4, 6, and 8 were stored at 80 °C and analyzed for the content of AITC, its isomerization product allyl thiocyanate (ATC), and 9 other decomposition products. The major reaction products in alkaline buffers were allylamine (AA), allyl dithiocarbamate (ADTC), diallylthiourea (DATU), and carbon disulfide (CDS). CDS and AA also arose as the major products in buffers of pH 6 and 4. Newly identified decomposition products of AITC were ADTC, diallylurea (DAU), and diallyl sulfide (DAS). Mechanisms explaining the decomposition of AITC are presented and discussed.
