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: TWCCSN2 value of 217.3 Å2 [M+Na]+

The collision cross section (CCS) measurement was provided by Waters Corporation, using the SYNAPT XS mass spectrometer.
For a description and overview of how ion mobility enables the measurement of the CCS of an ion visit ims.waters.com.
Further information on the SYNAPT XS mass spectrometer can be found on the IMS microsite and product webpage.

TWCCS measurements are expected to be within 2% of this reference value.
