Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of histamine H2 receptor antagonists. It plays a key role in creating compounds that help reduce gastric acid secretion, making it valuable in treating ulcers and gastroesophageal reflux disease (GERD). Its structure supports the design of bioactive molecules with improved stability and binding affinity. Also explored in agrochemicals for developing plant growth regulators and fungicides due to its heterocyclic backbone.
