A modular approach towards a series of novel di azido, tetra azido and hexa azido esters is introduced here. The methodologies adopted towards their synthesis are short, environmentally friendly, cheap and scalable. Detailed computational, physical and thermal studies of these plasticizers with binders have been carried out. Our results reveal impressive properties in terms of thermal stability, sensitivity, nitrogen content, oxygen balance, kinetics and heat of formation of synthesized plasticizers and their compatibility with energetic binders.
