WebBenzocaine is the ethyl ester of p -aminobenzoic acid (PABA). It can be prepared from PABA and ethanol [26] by Fischer esterification or via the reduction of ethyl p -nitrobenzoate. Benzocaine is sparingly soluble in water; it is more soluble in dilute acids and very soluble in ethanol, chloroform, and ethyl ether.
