Abstract: A method was developed for the detn. of the acetate or benzoate of 7-dehydrocholesterol in the reaction mixt. from the synthesis of vitamin D3. The steroid matter is detd. by spectrophotometry after the sepn. (EtOH elution). The deviation of the method is 1.6% for 7-dehydrocholesterol benzoate.
