Abstract: Described herein is a method for preparing an amino salt compound, the method including: i) providing a carbonyl compound; ii) reacting the carbonyl compound provided according to (i) in the presence of a transaminase with ii-a) at least one primary amine; and ii-b) at least one carboxylic acid; thereby obtaining a mixture including an at least partially crystallized amino salt compound including a cation and a carboxylate anion based on the at least one carboxylic acid added according to (ii-b). Also described herein is an amino salt compound obtained or obtainable by the method and to the amino salt compound, and a composition including a) an amine of general formula (IIa); and b) at least one carboxylic acid of general formula (III).
