It is the active ingredient in many over-the-counter anesthetic ointments such as products for oral ulcers. It is also combined with antipyrine to form A/B otic drops to relieve ear pain and remove earwax. == Chemical properties == 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 88–90 °C,〔(【引用サイトリンク】title=Monographs: Pharmaceutical substances: Benzocainum – Benzocaine )〕 and the boiling point is about 310 °C.〔D'Ans-Lax, Taschenbuch für Chemiker und Physiker, 4. Auflage, Band 2, Springer Verlag 1982, ISBN 3-540-12263-X〕 The density of benzocaine is 1.17 g/cm3. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Benzocaine」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
