INDEX NAME NOT YET ASSIGNED

(±)-Jasmonic acid-d₅ 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.²
