LC-MS analysis data of intermediate products used to construct photodegradation pathways for...

The photolysis of bis(1H-tetrazol-5-yl)amine (H₂BTA) in water was carried out in SolSim and Rayonet photochemical reactors equipped with solar simulating and ultraviolet lamps, respectively. The intermediary degradation products were monitored and tentatively identified by liquid chromatography - mass spectrometry (LC-MS). A quadrupole time-of-flight mass spectrometer (QTOF) was used to measure the mass-to-charge ratio (m/z) of the deprotonated molecular ions ([M - H]^-) using electrospray ionization in negative mode (ESI-), thus making it possible to determine the number of C, H, N and O in the molecules. Four major degradation products, namely N-(1H-tetrazol-5-yl)formamide (T(5yl)FA), 1H-tetrazol-5-ylcarbamic acid (T(5yl)CA), N-(1H-tetrazol-5-yl)carbamohydrazonic acid (T(5yl)CHA) and 1H-tetrazol-5-amine (5-AT), have been identified after solar simulated and UV irradiation. This dataset is supplementary to the research paper "Photodegradation of bis(1H-tetrazol-5-yl)amine (H₂BTA), a high nitrogen content tetrazole-based energetic compound in water" [1].
