(±)-Jasmonic acid-d
5 is intended for use as an internal standard for the quantification of jasmonic acid by GC- or LC-MS. Jasmonic acid (JA) is a plant growth regulator and derivative of α-linolenic acid that can exist in four stereoisomeric forms.
1,2 (–)-3(R),7(R)-JA and (+)-3(S),7(S)-JA have the two side chains in the
trans configuration, whereas (–)-3(S),7(R)-JA and (+)-3(R),7(S)-JA have the two side chains in the
cis configuration, which can epimerize at C7 to the
trans configuration
via keto-enol tautomerization.
