BCTC is primarily used as a TRPM8 (Transient Receptor Potential Melastatin 8) channel antagonist. It is widely applied in research to study the role of TRPM8 in various physiological processes, particularly in relation to cold sensation and pain. BCTC helps in understanding mechanisms of cold-induced pain and is used in experimental models to explore potential therapeutic targets for conditions like neuropathic pain and cold allodynia. Additionally, it is utilized in dermatology research to investigate its effects on skin sensitivity and irritation. Its ability to block TRPM8 channels makes it a valuable tool in developing treatments for cold-related discomfort and hypersensitivity.
