Thermoanalytical Behaviour of 2-amino- and 2-oxo- Substituted Pyrimidines

Abstract

Thermoanalytical behaviour of 2-amino-and 2-oxo-substituted pyrimidines studied in an inert atmosphere (N 2) has been described. The simultaneous TG-DTA profiles recorded over the temperature range of ambient-700EC, with a heating rate programmed at 10EC/ min, indicate fairly resolved mass loss stages and peaks. The thermal stability and degradation pattern of the substituted pyrimidines is discussed.
