Used as an intermediate in organic synthesis, particularly in the preparation of nitrogen-containing heterocyclic compounds. It serves in the pharmaceutical industry for constructing active pharmaceutical ingredients where the aminomalononitrile moiety acts as a building block for pyrimidine and triazine derivatives. Also applied in agrochemical synthesis for developing herbicides and plant growth regulators. Its sulfonate form enhances stability and handling during reactions, making it suitable for controlled condensation and cyclization processes.
