Solubility of benzocaine in water
WebBenzocaine. Molecular Formula CHNO. Average mass 165.189 Da. Monoisotopic mass 165.078979 Da. ChemSpider ID 13854242. Benzocaine is the ethyl ester of p-aminobenzoic acid (PABA). It can be prepared from PABA and ethanol 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. The melting point of benzocaine is 88–92 °C, and the boiling point is about 310 °C. The density of benzocaine is 1.17 g/cm .
