| General description: | Methyl stearate is a solid, saturated fatty ester, which can be prepared from methyl oleate via catalytic hydrogenation. |
| Other Notes: | Ion Mobility: TWCCSN2 value of 191.4 Å2 [M+H]+ 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. P/N 85769 is part of the Waters Extractables & Leachables UNIFI scientific library which can be downloaded from Waters Marketplace. |
