COMMENT: This record was created by the financial support of MEXT/JSPS KAKENHI Grant Number 22HP8019 to the Mass Spectrometry Society of Japan.
COMMENT: Original ID of the mass spectral data is 2201a2T2_ei.xlsx.
COMMENT: JMS-T100GCV (JEOL, Akishima, Japan) is a reflectron time-of-flight (reTOF) mass spectrometer. Temperature of the ion-source and GC-transfer line were 200 C and 250 C, respectively. Resolving power (FWHM, nominal) was 7000.
COMMENT: EI voltage was 70 V. Typical accuracy level expected was 5 ppm. The m/z value was adjusted with 316.21281.
