A facilesynthesis is described for [3,4,1′-13C3]genistein for use as an internal standard in isoflavone analysis by mass spectrometric methods. Ethyl 4-hydroxy[1-13C]benzoate was first prepared from the reaction of diethyl [2-13C]malonate and 4H-pyran-4-one. Two further 13C atoms were incorporated using potassium [13C]cyanide as the source to give 4′-benzyloxy-[1,2,1′-13C3]phenylacetonitrile. [3,4
