Abstract
Abstract Novel steroids of the formula WHEREIN X is selected from the group consisting of O and, Y is selected from the group consisting of hydrogen and -OH and when R1 is -(CH2)a-COOH in which a is equal to 2n + 3 and n is 0, 1 or 2, R2 is and when R1 is hydrogen, R2 is selected from the group consisting of AND N-Z-(CH2)c-COOH, b is a number from 3 to 18, c is a number from 1 to 8 and Z is selected from the group consisting of -Oand -NHCONH- which are haptenes or compounds capable of producing antibodies in vitro but are derived of antigenic properties and their preparation.
