Used primarily as an antifibrinolytic agent to prevent the breakdown of blood clots, especially in surgical settings to reduce bleeding. Commonly applied during procedures like cardiac surgery, dental operations in patients with hemophilia, and other surgeries where excessive bleeding is a concern. Also used to manage heavy menstrual bleeding (e.g., due to uterine fibroids), in cases of trauma or hemorrhagic shock, and to reduce bleeding in the urinary tract, particularly after urological procedures. In biochemical research, it serves as a protease inhibitor to protect proteins during purification and extraction. Additionally, it acts as an intermediate in the synthesis of nylon-6, contributing to polymer production in industrial applications.
