The use of tetramethylammonium hydroxide in the Zimmermann reaction [PDF]
Journal of Clinical Pathology, 1961 The use of tetramethylammonium hydroxide (T.M.A.H.) in place of potassium hydroxide in the Zimmermann reaction has been investigated. Although various pure steroids have different colour equivalents, a comparison of the results of 17-ketosteroid and 17-hydroxycorticosteroid estimations on a series of urines showed that the differences for the two ...
