A study of the kinetics and products of the decomposition of the carcinogen N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in aqueous buffered solutions, 1 M ionic strength at 40 o C, has been carried out over the range pH 4-10. The pK a of MNNG has been determined to be 7.73±0.03. Rate constants k int for the buffer-independent, solvolytic, decomposition reaction increase with increasing pH above pH
