Using non-isothermal kinetic data, thermal stability of 5-aminotetrazole de
rivative was calculated in the temperature range 200-250 degrees C. The inf
luence of inductive and mesomeric effects on the stability of 5-aminotetraz
ole ring was investigated. It was established, that the substituents in pos
ition "1" of 5-aminotetrazole ring, having negative inductive effect, decre
ase its thermal stability, while the substituents showing positive inductiv
e effect increase it.
