Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for nitrogen-containing heterocycles due to its reactive guanidine group. Commonly employed in the development of bioactive molecules, including antimicrobial and antifungal agents. Also utilized in the synthesis of dyes and functional materials where basic or coordinating properties are required. Its aromatic toluidine moiety enhances stability and influences electronic characteristics in final compounds.
