Preparation of methyl carbon 14 labeled docosa 7 10 13 16 tetraenoate

, : Preparation of methyl carbon 14 labeled docosa 7 10 13 16 tetraenoate. Journal of Labelled Compounds & Radiopharmaceuticals 19(9): 1063-1070

Methyl[1-14C]docosa-7,10,13,16-tetraenoate [important to the development of testicular tissue] was prepared from [1-14C]arachidonic acid by 2 successive Arndt-Eistert syntheses which could also be used for the step-wise homologation of other labeled fatty acids. After purification by gas chromatography the specific activity was 6.16 mCi/mmol, and the radiochemical purity was 97%.
