There is provided a method of producing novel 13C-labelled estrogen analogues. The method preferably proceeds via an intermediate A or B or which is a mixture of (A) or (B): wherein a13C atom is located at one or more of positions 1, 2, 3 or 4 and wherein R is an optionally substituted alkane, alkene, alkyne or aryl group. Preferably R is -CH2Ph. An alternative preferred intermediate compound is 13C-resorcinol.
