Antirhine is primarily used in the field of organic synthesis and pharmaceutical research. It serves as an intermediate in the preparation of various biologically active compounds, particularly alkaloids and heterocyclic molecules. Due to its structural similarity to certain natural products, it is employed in the development of potential therapeutic agents, including those with neuroactive and antimicrobial properties. Antirhine derivatives are also investigated for their role in enzyme inhibition and receptor modulation, making them valuable in drug discovery. Additionally, it finds use in academic and industrial research for studying reaction mechanisms and stereochemistry in synthetic pathways.
