Method for analyzing deuterated benzenes, method for selecting deuterated benzene for deuterated compound preparation, and method for preparing deuterated compound

A method for analyzing deuterated benzene, the method comprising:

• step (1) separating deuterated benzene by gas chromatography, and then deriving a peak height for each of 78 m/z to 84 m/z of the deuterated benzene based on an individual mass chromatogram of an isotope having a different mass number obtained by a mass analysis;
• step (2) separating each of a benzene-d0 reference standard, a benzene-d1 reference standard, a benzene-d2 reference standard, a benzene-d3 reference standard, a benzene-d4 reference standard, a benzene-d5 reference standard and a benzene-d6 reference standard by gas chromatography, and then calculating a peak height for each of 78 m/z to 84 m/z of each of the benzene-d0 to benzene-d6 reference standards based on an individual mass chromatogram of an isotope having a different mass number obtained by a mass analysis;
• step (3) calculating an inverse matrix of a value obtained by normalizing the peak height for each of 78 m/z to 84 m/z of each of the benzene-d0 to benzene-d6 reference standards;
• and
• step (4) calculating a value obtained by deconvoluting the peak height for each of 78 m/z to 84 m/z of the deuterated benzene through the following Equation 1:
• Deconvoluted peak height(i)=Ki(benzene-d0)×H(84m/z)+Ki(benzene-d1)×H(83m/z)+Ki(benzene-d2)×H(82m/z)+Ki(benzene-d3)×H(81m/z)+Ki(benzene-d4)×H(80m/z)+Ki(benzene-d5)×H(79m/z)+Ki(benzene-d6)×H(78m/z) [Equation 1]
• in Equation 1,
• i means 78 m/z, 79 m/z, 80 m/z, 81 m/z, 82 m/z, 83 m/z or 84 m/z;
• K means an inverse matrix value for each of 78 m/z to 84 m/z of each of the benzene-do reference standard, the benzene-d1 reference standard, the benzene-d2 reference standard, the benzene-d3 reference standard, the benzene-d4 reference standard, the benzene-d5 reference standard and the benzene-d6 reference standard calculated in step (3);
• and
• H means the peak height for each of 78 m/z to 84 m/z of the deuterated benzene derived in step (1).
