Tetracaine Hydrochloride (CAS 136-47-0)

Tetracaine Hydrochloride (CAS 136-47-0) is a potent ester-type local anesthetic and calcium channel blocker, widely used for topical anesthesia in ophthalmology (eyes) and for spinal anesthesia due to its ability to block voltage-gated sodium channels and inhibit calcium release. Available as a powder or in solutions, it’s known by trade names like Pontocaine, acts rapidly to numb tissues, and is also used in research as a channel inhibitor.
