ABSTRACT
Some new pyrazolo-quinazolines have been synthesized and characterization of the
synthesized was done by IR, NMR and mass spectral data. The thermal properties of some synthesized
compounds were studied by TGA and DSC methods. From the thermo grams, thermal stability and
some kinetic parameters such as energy of activation, frequency factor, order of reaction and entropy
of activation were evaluated. It is observed that for all the studied compounds, degradation is single
step process. Thermal stability varies slightly according to the nature and position of the substitutions
present in the studied compounds.
