Moore, Erich Heftmann, Chapter 2: Chemistry of the adrenocortical steroids, Helen Wendler Deane, The Adrenocortical Hormones, Part 1, Springer-Verlag, page 221, The 21-hydroxyl group in the α-ketol side chain is very easily esterified, and in many of the synthetic routes leading to these side chains the ketol acetate is still formed.

   The steroid acetates are stable derivatives, having the desirable property that the electron-capture detector (ECD) selectively responds to acetyl derivatives of α-ketols [958].
