QAQ dichloride (Cat No.:I011212) is a synthetic, photoswitchable ion channel blocker designed for optogenetic and neuropharmacological research. Its azobenzene core undergoes reversible cis–trans isomerization under specific light wavelengths, enabling light-controlled modulation of neuronal ion channels. By providing spatiotemporal precision in blocking ion flux, QAQ dichloride is widely used to study neuronal excitability, synaptic transmission, and neural circuit function. This compound offers a powerful tool for probing ion channel physiology and developing photoresponsive approaches in neuroscience, pain research, and targeted photopharmacology.
