All reagents for syntheses were purchased from commercial sources. Thermogravimetric (TGA) analyses were investigated with a Mettler Toledo TGA/SDTA851 analyzer (Mettler Toledo, Zurich, Switzerland) in N2 atmosphere with a heating rate of 5 K min−1, from 30 °C to 800 °C. Elemental analyses (C, N, H) were measured on an Elementar Vario EL III microanalyzer (Elementar, Frankfurt, Germany). IR spectra were measured from a KBr pellets on a Thermo Scientific Nicolet IS10 FT-IR spectrometer (Thermo Scientific, Waltham, MA, USA) in the range of 4000–400 cm−1. Powder X-ray diffraction (PXRD) patterns were carried out using a Bruker D8 powder diffractometer (Bruker, Karlsruhe, Germany) at 40 kV, 40 mA for Cu Kα radiation (λ = 1.5406 Å), with a scan speed of 0.2 s/step and a step size of 0.05° (2θ).

Hexane (95%), thiosemicarbazide (98%) was purchased from Sigma-Aldrich (St. Louis, MO, USA). HM was prepared in the Medicinal and Process Chemistry Division of Central Drug Research Institute, Lucknow, Uttar Pradesh, India. Milli-Q pure water was obtained from a Millipore Elix water purification system (Millipore India Pvt. Ltd., New Delhi, India). high-performance liquid chromatography (HPLC) grade methanol and acetonitrile (ACN) were purchased from Merck Ltd., (Mumbai, India). IR spectra was recorded using potassium bromide (KBr) discs, on a PerkinElmer Spectrum RX1 infrared (IR) spectrophotometer. 1H and 13C nuclear magnetic resonance (NMR) spectra were recorded in dimethyl sulfoxide (DMSO) on Bruker DRX-300 (400 MHz) and JEOL AL300 Fourier transform (FT)-NMR (400 MHz) systems; chemical shift (d) is reported in ppm using tetramethyl silane as an internal reference. Mass spectra were recorded on Agilent 6520 mass spectrometer. Elemental analysis was performed on Elementar's Vario EL III micro-analyzer.

All chemicals can be commercially
obtained and used without further purification. TGA and DSC data were
collected using a Mettler Toledo instrument under a N2 atmosphere
with 2.7 mg power of the samples heated in an Al2O3 crucible at a linear heating rate of 5 K min–1. Elemental analyses were performed on an Elementar Vario EL III
microanalyzer. The Fourier transform infrared spectra were recorded
on a PerkinElmer Spectrum using KBr pellets. The temperature-dependent
molar magnetic susceptibilities were calculated on a Quantum Design
MPMS-XL SQUID magnetometer using crushed samples (in the powdered
form). IS and FS were measured on a BAM fall hammer BFH-12 and a BAM
friction apparatus FSKM-10, respectively, calibrated by manufacturers
using traditional energetic materials such as TNT, RDX, and HMX. Powdered
X-ray diffraction (PXRD) patterns were recorded on a Rigaku Miniflex

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
