Abstract 1,3,5‐trinitroso‐1,3,5‐triazine (R‐Salt) is an insensitive energetic that has previously been used as an improvised explosive. The work presented here is a comprehensive study on the thermal properties and chemical characterization of R‐Salt. Thermal analysis was performed via differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) which found both crude and recrystallized R‐Salt have similar thermal properties but the selected lid impacted both the thermal profile and onset temperature. Chemical characterization performed via Raman, Fourier‐transform Infrared (FT‐IR), nuclear magnetic resonance (NMR) spectroscopy and high‐resolution mass spectrometry indicate that recrystallization does not quantitatively improve the purity of crude R‐Salt., The reported NMR 2D‐HSQC, FT‐IR, and Raman spectra are the first to be reported within the published literature, as to the authors’ knowledge.
