Used primarily as a synthetic analog of capsaicin in research and pharmaceutical applications. It activates the TRPV1 receptor, making it valuable in studies related to pain perception and desensitization of sensory neurons. Commonly employed in topical formulations to relieve neuropathic pain, arthritis, and muscle soreness. Also utilized in cosmetic products to induce a warming sensation, promoting increased blood flow and skin absorption. Its controlled irritant properties make it suitable for use in self-defense sprays and animal repellents. Frequently used in laboratory settings to study ion channel function and nociception mechanisms.
