Tetracaine hydrochloride
Tetracaine hydrochloride (CAS 136-47-0), with the molecular formula C15H24N2O2 · HCl and a molecular weight of 300.82 g/mol, is a potent local anaesthetic. It functions by blocking sodium ion channels, thus preventing nerve impulse propagation. Primarily utilised as a topical ophthalmic anaesthetic for eye procedures, it has also been employed for spinal anaesthesia. TSS offers this compound with an assay of ≥99%.

Topical Ophthalmic Anaesthesia
Tetracaine hydrochloride is widely used as a surface anaesthetic in ophthalmology. It provides rapid and effective pain relief for diagnostic and minor surgical procedures on the eye.
Spinal Anaesthesia
Historically, tetracaine hydrochloride has been administered intrathecally to produce spinal anaesthesia for surgical procedures. Its use in this application requires careful medical supervision.
Research and Development
As a known ion channel modulator, tetracaine hydrochloride serves as a valuable tool in pharmacological research for studying nerve impulse transmission and pain mechanisms.
