Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of thiamine (vitamin B1), which is essential for the functioning of the nervous system and energy metabolism in the body. It serves as a building block in the preparation of pyrimidine-based drugs due to its reactive amino and hydroxyl groups. Also employed in research for developing new bioactive compounds, including those involved in enzyme or neurotransmitter control, and in the manufacture of certain agrochemicals. Its hydrate form enhances stability during storage and handling in industrial processes.
