Benzocaine hydrochloride（Cat No.:I047187）is a water-soluble salt form of benzocaine, a local anesthetic with the molecular formula C9H11NO2·HCl. It works by blocking sodium channels on nerve membranes, preventing the initiation and transmission of nerve impulses, thereby producing a numbing effect. Commonly used in topical formulations, lozenges, and dental gels, benzocaine hydrochloride provides rapid but short-acting relief from pain, itching, sore throat, or gum irritation. It is favored for mucosal applications due to its enhanced solubility. Overuse or hypersensitivity may cause side effects such as methemoglobinemia or localized allergic reactions.
