Other Notes

Chemcial Shift: 8.1 and 3.9 ppm (chemical shifts may slightly vary depending on the experimental conditions)
Suitable NMR solvents: Acetonitrile, Chloroform, MeOD, DMSO-d₆

Ion Mobility: ^TWCCS_N2 value of 217.3 Å2 [M+Na]⁺

The collision cross section (CCS) measurement was provided by Waters Corporation, using the SYNAPT XS mass spectrometer.
