CAS 136-47-0 Tetracaine HCl Alias: Tetracaine hydrochloride, TetracaineHCL;pontocaineCAS NO.: 136-47-0EINECS: 205-248-5MF: C15H25ClN2O2MW: 300.82Melting point: 149CAssay: 99%Grade: Pharmaceutical GradeStorage: Closed, confined and shading preservationUsage: Local anesthetic; Mainly used in mucosa anesthetic. The function is stronger than Procaine and Lidocaine.Catergory: API intermediates;local anesthetic;Sodium channel;Amines;Aromatics;Intermediates & Fine Chemicals;Pharmaceuticals;Pharmaceutical intermediate;pharmaceutical raw material;cytobiology; Description: Tetracaine HCl is synthesized from 4-butylaminobenzoic acid. The ethyl ester is formed through an acid-catalyzed esterification reaction. Base-catalyzed transesterification is achieved by boiling the ethyl ester of 4-butylaminobenzoic acid with excess 2-dimethylaminoethanol in the presence of a small amount of sodium ethoxide.
