The present invention provides a method for making 6-aminocaproic acid as an active pharmaceutical ingredient. The method comprises: performing a hydrolysis procedure to have ε-caprolactam react with acid or base to generate a first reaction mixture, performing a modification procedure to have a solubility regulating agent reacts with 6-aminocaproic acid in the first reaction mixture to form a second reaction mixture including an aminocaproic acid intermediate, performing a separation procedure to have the intermediate separated from the second reaction mixture and performing a hydrogenation procedure to have the aminocaproic acid intermediate hydrogenated to form a 6-aminocaproic acid product.
