Used primarily as a selective TRPA1 (Transient Receptor Potential Ankyrin 1) channel antagonist in scientific research. It helps investigate the role of TRPA1 channels in pain signaling, inflammation, and neurogenic responses. Commonly applied in studies related to neuropathic pain, migraine, and respiratory conditions such as asthma and chronic cough, where TRPA1 activation contributes to symptoms. Due to its ability to cross the blood-brain barrier, it is also utilized in central nervous system research to explore pain modulation and neuronal excitability. Widely used in preclinical models to evaluate potential therapeutic targets for pain management and inflammatory diseases.
