| Description | Hexylcaine, also known as cyclaine, belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. Hexylcaine is a drug which is used as a local anesthetic for surface application, infiltration or nerve block. Hexylcaine hydrochloride, also called cyclaine (Merck) or osmocaine, is a short-acting local anesthetic. Hexylcaine is a very strong basic compound (based on its pKa). |
