Chemically known as the ethyl ester of , benzocaine is typically synthesized through Fischer esterification . In a laboratory setting, this involves reacting 4-aminobenzoic acid with absolute ethanol in the presence of a strong acid catalyst, such as concentrated sulfuric acid. In a laboratory setting

Benzocaine is versatile, appearing in various over-the-counter and professional medical formulations, including gels, sprays, creams, and lozenges. Benzocaine - StatPearls - NCBI Bookshelf - NIH
