A synthetic route to 3,5-dinitropyridine analogs and evaluation of their thermal properties

The search for new energetic materials that balance overall performance with stability has been at an increased demand over the past decade. Synthetic efforts towards this pursuit are often tedious and slow, resulting in hindered progress in this area of exploration. Thermal analysis studies such as differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) are fundamental experiments that can be used to gain preliminary kinetic information to provide insights into the long-term stability of these materials, along with their stability toward harsh environments. This work describes synthetic routes to new 3,5-dinitropyridine-based materials, including initial DSC and TGA analysis on the compounds' energetic properties that we anticipate will be useful in constructing a more developed understanding of how molecular structure affects both energetic performance and overall stability.
