Abstract

See full text

A modified method for preparing guanidino acetic acid (GAA) involves reacting cyanamide with an excess molar amount of glycine in an aqueous reaction mixture, in the presence of a base. The method avoids high molar amounts of base or acid for pH control, and maintains the reaction selectivity and product yields.
